The following formula appears in one of our Smartsheets as a column formula:
=IF(Holidays@row <> "", IF(TODAY() >= Holidays@row, COUNTIFS({Course Complete Date}, Holidays@row, ""), ""))
This formula had been functioning as intended for quite some time, but it started yielding an #INCORRECT ARGUMENT SET error a few days ago. I checked the column mentioned in the formula (Holidays) as well as the reference ({Course Complete Date}, which points to an entire column in another Smartsheet), and they appear to be functioning correctly.
Does anyone know why this formula has started yielding an error?
