I am trying to create a approval process. In the approval process for action i wanted to create a new action with Field Update. In doing so i am prompted for a new page. After this nothing seems to happen. Attahced is the image. The only difference i see in this play ground is the Go button has to be clicked for creating a new action. 




 

I am getting the following errror when trying to complete 
Attributes and Expressions as part of develop for Ligthing experience.

Challenge Not yet complete... here's what's wrong: 
The Quantity field is either not using the lightning formattedNumber component or the value of the item's Quantity__c.


The code is as below

<aura:component>
   <aura:attribute name="item" type="Camping_Item__c" required="true"/>
     <p>Name:<ui:outputText value="{!v.item.Name}"/></p>
    <p>Price:<ui:outputCurrency value="{!v.item.Price__c}"/></p>
    <p>Quantity:<ui:outputNumber value="{!v.item.Quantity__c}"/></p>
    <p>Packed:<ui:outputCheckbox value="{!v.item.Packed__c}"/></p>
</aura:component>
 

Trying to complete the "HUNT YOUR PROSPECT" unit, getting the following error message when i try to complete the creation of the Opportunity:

"Challenge Not yet complete... here's what's wrong: The record was not created correctly"
Unless there are invisible steps in this Trailhead, I have completed them all.
Is it possible this trailhead has an error?
