auto enter modification date on field change

[DblWide]

I need to track stages of a project. For each step, I have a "completed by" field and a "completed on" field. When a person enters their initials in the "completed by" field I want the date to auto enter in the "completed on" field.

I can't figure out the calculation. I searched the archives but didn't find an answer. Thanks in advance for your help!

I think Case( completed_by; Get(CurrentDate) ) should work. Make sure it's stored.

Still not working. FM will accept the calculation, but when I enter info into the "completed by" field, nothing appears in the "date completed" field. Any other ideas?

Sorry, I should have said Case( not IsEmpty(completed_by); Get(CurrentDate) ).

Works like a charm! Thanks!
