I'm working through this unit https://trailhead.salesforce.com/modules/lightning_app_builder/units/lightning_app_builder_recordpage?trailmix_creator_id=005500000060g68AAA&trailmix_id=lightning-trailblazer and I can't get past the challenge.  It says it can't find a Twitter component but it's definitely there.  I even logged into Twitter and linked it to the Account to see if that would resolve the issue.  I've seen some other posts about problems with this Challenge but no one specifically mentions the Twitter component.  Thanks!

I can't find the peices necessary (underlined) to complete this trail.

Hello All,
I have completed this challenge.

1-For this first you need to create a helper formula field(type-percent) 
Percent Completed :
(DATEVALUE( CreatedDate ) - CloseDate )/100

2- Then you need to create the actual formula field (type- text) by using the helper formula field.
Opportunity Progress :

IF( Percent_Completed__c <=25,"Early", 
IF(Percent_Completed__c <=75,"Middle", 
"Late"))

Thanks,
Nida


 

The validation rule should be on the Case object.
The validation rule should be named 'Mark_as_Escalated'.
The validation rule should fire if someone tries to set a case as escalated and it is closed, closed when created, or does not have a priority of High.
The validation rule should display the error message 'You can only set a case as escalated if it is high priority and not closed' under the Escalated field when triggered.
Add the 'Escalated' field to the Case page layout.
