Hi All, I am having problem in resolving an error in the 'Customization Specialist superbadge' . The error message is 'The '# of Volunteers Still Needed' field on the 'Volunteer Shift' record is not working as expected'. I have tried all the options
i.e. IF( Desired_of_Volunteers__c - Shifts_Taken__c > 0, Desired_of_Volunteers__c - Shifts_Taken__c , 0) 

and Max(Desired_of_Volunteers__c - Shifts_Taken__c,0) also.
But no luck .So it's now no more fun!!  Kindly help me in solving this soon ...
