I have put this formula into a text/number cell and it is working on all lines EXCEPT the lines that match "To Aim Spraypainters" and have the Install/Pickup date prior to today. I have checked that the spelling of the text matcheS the column heading and its correct.
=IF(OR([Factory Completed]@row = 1, AND(Description@row = "To Aim spraypainters", [Install/Pickup date]@row < TODAY(-1))), -[Total production time]@row, 0)
Any help will be gratefully received 🙂
