This seems pretty elementary, but I can't figure out how to do it.
I have a form with a person field (Person_A). if that field has a value in it, I want to send them an email, otherwise I want to use the CreatedBy field. I'm having troubles assembling the combination of logic to do this.
Basically, if not(empty(Person_A)) then do this, otherwise do this.
Any guidance is appreciated.
