I'm working on the below link trailhead. 

I'm not able to understand what's needs to be done on the step 2. 

1.Create a new Lightning component named myEverythingComponent
2. Add this static text to the component: I'll have one with everything
3. Add each resource type to the component, by clicking Create for each resource type: Controller, Helper, Style, Documentation, Renderer, Design, SVG

can someone please assist me on this? 
Re-factored my code from previous units with base lightning components, but receiving this error.  Here's my new form component.  Any help would be much appreciated.

<aura:component >   
    <aura:attribute name="newItem" type="Camping_Item__c"    default="{ 'sobjectType': 'Camping_Item__c',
                         'Name': '',
                         'Price__c': 0,
                         'Quantity__c': 0,                         
                         'Packed__c': false
    <aura:registerEvent name="addItem" type="c:addItemEvent"/>
    <lightning:layout >
        <lightning:layoutItem padding="around-small" size="6">
<div aria-labelledby="newItemForm">

    <!-- BOXED AREA -->
    <fieldset class="slds-box slds-theme--default slds-container--small">

    <legend id="newItemForm" class="slds-text-heading--small 
      Add Camping Item

    <form class="slds-form--stacked">          
        <lightning:input aura:id="itemForm" label="Camping Item Name"
        <lightning:input type="number" aura:id="itemForm" label="Quantity"
        <lightning:input type="number" aura:id="itemForm" label="Price"
                         messageWhenRangeUnderflow="Enter an amount that's at least .01."/>
        <lightning:input type="checkbox" aura:id="itemForm" label="Packed?"  
        <lightning:button label="Create Expense" 
  <!-- / BOXED AREA -->

When checking this challenge, I get an error stating that the quickContact Lightning Component could not be found. Including screenshots of the steps I took thus far. Any advice would be appreciated!

1. The Lightning component must be named quickContact (this comes as part of the package, confirmed in picture below)
User-added image

2. Create a new action with Label Quick Contact and Name Quick_Contact on the Account object that invokes the quickContact component. (confirmed in picture below)
User-added image
3. Add the appropriate interfaces to the quickContact component. (Hint: there are two.) (used the implements force:lightningquickaction AND the force:hasrecordid on line 1, confirmed in picture below)
User-added image

4. Add the action to the Account Layout page layout. (added in picture below)
User-added image
    Eventhough my code works i still get the error "The page does not bind to the record ID value (in order to link to the record detail page) " when i tried to check in the challenge. any help is appreciated.
code below:
<apex:page standardController="Account" recordSetVar="accounts" >
   <apex:pageBlock title="Account List">
      <!-- accounts List -->
       <apex:repeat value="{! accounts }" var="a">
            <apex:outputLink value="/{!LEFT(a.Id,15)}">/{!LEFT(a.Id,15)} </apex:outputLink>

For the above qus I wrote the below code : 

trigger ClosedOpportunityTrigger on Opportunity (after insert,after update) {

List<Task> t1=new List<Task>();

for (opportunity a :[select ID,StageName  from opportunity where StageName='Closed Won' and ID IN :Trigger.New])

t1.add(new Task(subject= 'Follow Up Test Task', WhatId=a.ID));

if(t1.size() >0 && t1.size()<=200)
insert t1;

But getting a error like   :
Challenge Not yet complete... here's what's wrong: 
There was an unexpected error in your org which is preventing this assessment check from completing: System.DmlException: Insert failed. First exception on row 0; first error: CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY, trig_conts_opprty: execution of AfterInsert caused by: System.DmlException: Insert failed.

Anyone please tell me the possible reason for the error ?
I am having issues with Creating  an Apex class that returns Account objects for the Mapping.net concepts challenge.  I am a VB and Javascript programmer and I can't seem to get the syntax right.   
public class AccountUtils {
    public static void accountsByState(String st){
       List<String> accts = [SELECT Id, Name FROM Account WHERE billingState = :st];
I believe the first part is correct, but I cannot seem to get a return value.  I am confused by the constructors.  I have tried the documentation but I can't get a return value.  Please help.  I need to get this challenge complete.
Hi All,

Hello everyone I could use some help on the using future Methods trailhead. Please keep in mind I am not an Apex coder at all but I am trying to learn as much as I can.

Here is the Task

Create an Apex class with a method using the @future annotation that accepts a List of Account IDs and updates a custom field on the Account object with the number of contacts associated to the Account. Write unit tests that achieve 100% code coverage for the class.
Create a field on the Account object called 'Number_of_Contacts__c' of type Number. This field will hold the total number of Contacts for the Account.
Create an Apex class called 'AccountProcessor' that contains a 'countContacts' method that accepts a List of Account IDs. This method must use the @future annotation.
For each Account ID passed to the method, count the number of Contact records associated to it and update the 'Number_of_Contacts__c' field with this value.
Create an Apex test class called 'AccountProcessorTest'.
The unit tests must cover all lines of code included in the AccountProcessor class, resulting in 100% code coverage.
Run your test class at least once (via 'Run All' tests the Developer Console) before attempting to verify this challenge.

I have written an Apex class and a Test class but I think I am doing them both Wrong: because when I try to check the challenge i Get this error

Challenge Not yet complete... here's what's wrong: 
The 'AccountProcessorTest' test class doesn't appear to be calling the 'AccountProcessor.countContacts' method between Test.startTest() and Test.stopTest().

When I run the Test class I get this error :

System.QueryException: List has no rows for assignment to SObject

Here is the CLASS:
public class AccountProcessor {

  public static void someFutureMethod(List<id> scope) {

   Account[] updates = new Account[] {};
        for (AggregateResult ar : [
                select AccountId a, count(Id) c
                from Contact
                where AccountId in :scope
                group by AccountId
                ]) {
            updates.add(new Account(
                    Id = (Id) ar.get('a'),
                    Number_of_Contacts__c = (Decimal) ar.get('c')
        update updates;


Here is the Test Class:
public class AccountProcessorTest {
  public static testmethod void TestAccountProcessorTest() {
     Account a = new Account();
        a.Name = 'Test Account';
        Insert a;
      Contact cont = New Contact();
      cont.FirstName ='Bob';
      cont.LastName ='Masters';
      cont.AccountId = a.Id;
      Insert cont;

    Test.stopTest() ;
     Contact ACC = [select AccountId from Contact where id = :a.id LIMIT 1];

        System.assert(Cont.AccountId != null);
        System.assertequals(cont.id, ACC.AccountId);


I have used alot or diffrent google searches to get me this far. But I have not Idea if Im even remotly close to the right answer or not.

Hi all,

I'm stuck in the Apex Integration Services - Apex SOAP Callouts challenge with the following message "The Apex class 'ParkLocator' does not appear to be calling the SOAP endpoint.".

Could you please advise ?

I am trying to solve the challange of the HTTP and Basic Callout module of Salesforce trailhead and I am having some queries in which you could point to the right direction:

1- The challange asked us to call this URL https://th-apex-http-callout.herokuapp.com/animals/:id in method getAnimalNameById... should that URL be in this form instead of the above https://th-apex-http-callout.herokuapp.com/animals?id ? Where id is a parameter in the URL.

2- When I tried to check the solution of the challange, Salesforce generated that error for me
"Challenge Not yet complete... here's what's wrong: 
Executing the 'getAnimalNameById' method on 'AnimalLocator' failed. Make sure the method exists with the name 'getAnimalNameById', is public and static, accepts an Integer and returns a String."
despite that my class implementation has this method declared as public static String as below in the code snippet:
public class AnimalLocator {
	public static String getAnimalNameById(Integer id) {
		Http http = new Http();
		HttpRequest request = new HttpRequest();
		HttpResponse response = http.send(request);
		List<Object> animals = NULL;
		String returnValue = NULL;
		// if the request was successful, then parse the JSON response
		if (response.getStatusCode() == 200) {
			Map<String, Object> result = (Map<String, Object>) JSON.deserializeUntyped(response.getBody());
			animals = (List<Object>) result.get('animals');
		if (animals.size() > 0 && animals != NULL && id < animals.size()) {
			returnValue = (String) animals.get(id);
		return returnValue;
	} // end getAnimalNameById method
} // end AnimalLocator class

I would appreciate your help in this post.

Thank you,

Create an Apex class that returns a list of contacts based on two incoming parameters: one for the number of contacts to generate, and the other for the last name. The list should NOT be inserted into the system, only returned. The first name should be dynamically generated and should be unique for each contact record in the list.The Apex class must be called 'RandomContactFactory' and be in the public scope.
The Apex class should NOT use the @isTest annotation.
The Apex class must have a public static method called 'generateRandomContacts' (without the @testMethod annotation).
The 'generateRandomContacts' method must accept an integer as the first parameter, and a string as the second. The first parameter controls the number of contacts being generated, the second is the last name of the contacts generated.
The 'generateRandomContacts' method should have a return type of List<Contact>.
The 'generateRandomContacts' method must be capable of consistently generating contacts with unique first names.
For example, the 'generateRandomContacts' might return first names based on iterated number (i.e. 'Test 1','Test 2').
The 'generateRandomContacts' method should not insert the contact records into the database.

I create a class as bellow

public class RandomContactFactory{
   public static List<Contact> generateRandomContacts(integer n,string lastnames){

       list<contact> c= [select  FirstName from contact where LastName =: lastnames limit : n ];
       return c;

but i'm getting error as below

Challenge not yet complete... here's what's wrong: 
Executing the 'generateRandomContacts' method failed. Either the method does not exist, is not static, or did not return the correct set of Contact records.

Please let me know where the issue?
Hi ,

Hi All,

Can anyone please help me with bellow challenge.

Create an Apex trigger for Account that matches Shipping Address Postal Code with Billing Address Postal Code based on a custom field.
For this challenge, you need to create a trigger that, before insert or update, checks for a checkbox, and if the checkbox field is true, sets the Shipping Postal Code (whose API name is ShippingPostalCode) to be the same as the Billing Postal Code (BillingPostalCode).The Apex trigger must be called 'AccountAddressTrigger'.
The Account object will need a new custom checkbox that should have the Field Label 'Match Billing Address' and Field Name of 'Match_Billing_Address'. The resulting API Name should be 'Match_Billing_Address__c'.
With 'AccountAddressTrigger' active, if an Account has a Billing Postal Code and 'Match_Billing_Address__c' is true, the record should have the Shipping Postal Code set to match on insert or update.

For above challenge i tried with following code but looks like it doesnt mach the requirement.

trigger AccountAddressTrigger on Account (before insert, before update) {
    for(Account a : Trigger.new){
        If (a.Match_Billing_Address__c = true) {
            /*ShippingPostalCode = BillingPostalCode;*/


Please help me
