I am trying to create a formula that add the 'total pieces of media' if the 'type of media' is 'still' and the 'current / upcoming' is empty. The formula I am using is below and I keep getting invalid operation.
Not sure what I am doing wrong. Thank you for any help I can get. :)
=SUMIFS([Total Pieces of Media]:[Total Pieces of Media], [Type of Media]:[Type of Media] = "Still", [Current / Upcoming (USC/NARA)]:[Current / Upcoming (USC/NARA)], ISBLANK(@cell))
