Trying to do the above trailhead module (https://developer.salesforce.com/en/trailhead/point_click_business_logic/formula_fields#challenge)
I have a formula field returning text with the following formula:
IF( TODAY() > Brandon__SLAExpirationDate__c , 'true', 'false'  )

I have tested it on an account and when the SLA Expiry date  is in the past it shows true and when it is in the future it shows false.

When I check the challenge I get the following error
An account with an SLA date in the past returned an SLA expired of false (it should return true).

I have also tried with returning a checkbox.

Am I misunderstanding the requirements?

Hello.  I'm new to Salesforce and am following the tutorials in the Force.com Workbook.  The lesson is to create a flow to add a Line Item to an existing Invoice when you press a custom button. I am stuck on Step 7 - Try out the app (page 74 - Force.com workbook Summer' 14 edition). On click of button - "Add Line Item and Update Stock Qty" I am taken to the new flow screen, where I put in the values for Line Item Number, Merchandise, Quantity ordered and Unit Price; but I get the error

Add Line Item from Invoice and Update Stock Quantity
An unhandled fault has occurred in this flow
An unhandled fault has occurred while processing the flow. Please contact your system administrator for more information.

I am stuck at this for past one month. then left it, started the application all over again, but same error. I remember I tried debugging it earlier and found that there was an error in updating the Record. But am not sure how to do it again.

Any help will be highly appreciated.
