I have 2 fields in a list: Status and Revised Finish Date
I would like to make the 'Revised Finish Date' required if the 'Status' = Delayed, otherwise do nothing. I've tried to create a calculated field but my formula is incorrect:
=IF([Status]="Delayed", IsNot Null, " ")
Is my approach correct? If so, please help correct the formula. Otherwise can someone show me how I can accomplish this?
