The Name field is not being displayed using an expression.

Hi,
I am stuck on the Atttributes and Expressions challenge of the lightening component basics:

I get the following message: The Name field is not being displayed using an expression.

I'm really not 100% sure how the display component is meant to work for Name and Packed status - as there seems to be no "<lightening: /> formatting markup available. 

Here is my code:

<aura:component>

    <aura:attribute name="item" type="Camping_Item__c" required="true" />

    <aura:attribute name="expense" type="Expense__c"/>
    
    <p>Name: 
        <lightning:String value="{!v.item.Name__c}" style="Text"/>
    </p>
    
    <p>Price:
        <lightning:formattedNumber value="{!v.item.Price__c}" style="Currency"/>
    </p>
    
    <p>Quantity:
        <lightning:formattedNumber value="{!v.item.Quantity__c}" style="Number"/>
    </p>
    
    <p>Packed Status:
        <lightning:Checkbox value="{!v.item.Packed__c}" style="Toggle"/>
    </p>

</aura:component>

Thanks for your assistance in advance.

You could use lightning:formattedText component from here (https://developer.salesforce.com/docs/atlas.en-us.lightning.meta/lightning/aura_compref_lightning_formattedText.htm). There is no lightning:String component.

Also I suggest you double check field "Name" it's may not be a custom one, but standard Name field. Hope it would help.

Thanks but that did not work when I tried to save the .cmp 
I get the message: Failed to save campingListItem.cmp: The attribute "style" was not found on the COMPONENT markup://lightning:formattedText: Source

It would be something like this.

<lightning:formattedText  value="{!v.item.Name}" />

You may want to look at this API Documentation reference https://developer.salesforce.com/docs/atlas.en-us.lightning.meta/lightning/aura_compref_lightning_formattedText.htm (https://developer.salesforce.com/docs/atlas.en-us.lightning.meta/lightning/aura_compref_lightning_formattedText.htm). Would be very useful.

As you are supposed to display values using three different ways, my code shows one section for each of the three ways of displaying the required data.
