I have a formula that suddenly stopped working.


This formula has been in use for many months and has suddenly stopped working, and I'm getting an #INVALID OPERATION error.

=SUMIFS([Annual Revenue]:[Annual Revenue], [Project Type]:[Project Type], "Custom Courseware Solution", [Revenue Type]:[Revenue Type], "Delivered")

There are no formulas in the referenced columns. The Revenue Type is populated via an automation, but that has been in place since I started using the formula.

Any suggestions?

    @Andreea I was mistaken. There was a formula in one the "Annual Revenue" column. Someone had put "tbd" in a reference field which is what created the error. Would you happen to know if I can modify my formula to account for this, so if there is an error in the Annual Revenue field, the original formula noted in my first post just won't count it?

    The formula used in the Annual Revenue field is:

    =[Total $ (Per Student)]@row * [Actual Annual Seat Count]@row

    Thank you!!
