I am stuck on this trailhead. I followed all the steps but the Promote to Global Value Set button never appears. 
I see a number of people are having the same issue. What is the preferred solution?
Hi Team, I am trying to take challenges for Gus at Work in Trailhead, but i get an exception when clicked on the Check challenge. Could you please take a look at this one real quick?

Hi, I am having trouble with the "Attributes and Expressions" module from trailhead.

Here is the challenge:
Create a Lightning Component to display a single item for your packing list.
  • Create a component called campingListItem that displays the name (ui:outputText) and the three custom fields using the appropriate output components.
  • Add an attribute named 'item' for type Camping_Item__c.
I created an component named campingListItem and this is the code:
<aura:component >
    <aura:attribute name="item" type="<my_domain>__Camping_Item__c"/>
    <ui:outputText value="{!v.item.Name}"/>
    <ui:outputCheckbox value="{!v.item.<my_domain>__Packed__c}"/>
    <ui:outputCurrency  value="{!v.item.<my_domain>__Price__c}"/>
    <ui:outputNumber value="{!v.item.<my_domain>__Quantity__c}"/>

The error that I am getting is: "Challenge Not yet complete... here's what's wrong: 
The packingListItem Lightning Component's attribute tag doesn't exist or its attributes are not set correctly."

With this, I tried to create another component, with the name "packingListItem", but It didn't work.

Can anyone help me?


To pass this challenge, create an Apex class that inserts a new account named after an incoming parameter. If the account is successfully inserted, the method should return the account record. If a DML exception occurs, the method should return null.
The Apex class must be called 'AccountHandler' and be in the public scope.
The Apex class must have a public static method called 'insertNewAccount'.
The 'insertNewAccount' method must accept an incoming string as a parameter, name the account after the parameter, insert it into the system and then return the account record.
The 'insertNewAccount' method must also accept an empty string, catch the failed DML and return null.

Getting following Error message :

Challenge not yet complete... here's what's wrong: 
Executing the 'insertNewAccount' method failed. Either the method does not exist, is not static, or does not insert the proper account.

Following is the Code written for this ,any help is appreciated to complete the challenge

Public class AccountHandler{

public static List<Account> insertNewAccount(String firstname){

Account a=new Account();
insert a;

List <Account> queriedaccoutn = [SELECT Name 
                          FROM Account 
                          WHERE Name =:firstname 
                          LIMIT 1];
return queriedaccoutn;

The challenge is:

You've been given a requirement to keep Contact addresses in sync with the Account they belong to. Use Process Builder to create a new process that updates all child Contact addresses when the address of the Account record is updated. This process:Can have any name.
Must be activated.
Must update Contact mailing address fields (Street, City, State, Post Code, Country) when the parent Account shipping address field values are updated.

I start with Accounts when records is created or edited.
Filter criteria where accounts shipping address (street, city, state, zip code) is changed (used "or" logic).

I am stuck on the next step "add action".  I started with action type "Update Records".
On objects, I can't seem to change Accounts to Contacts.  Why?
