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 
      slds-p-vertical--medium">
      Add Camping Item
    </legend>

    <!-- CREATE NEW CAMPING ITEM FORM -->
    <form class="slds-form--stacked">          
        <lightning:input aura:id="itemForm" label="Camping Item Name"
                         name="Name"
                         value="{!v.newItem.Name}"
                         required="true"/> 
        <lightning:input type="number" aura:id="itemForm" label="Quantity"

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}"/>
</aura:component>

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?

Thanks,
