Hi!
I am trying to figure out the proper way to incorporate =ISNUMBER into my formula. I keep getting errors and can't figure out how quite to frame it in. I have a flag but I do not want it to flag blanks or text. I only want to flag duplicate numbers.
=IF(COUNTIFS([Site ID]:[Site ID], [Site ID]@row) + COUNTIFS([Device ID]:[Device ID], [Site ID]@row) + COUNTIFS([License ID]:[License ID], [Site ID]@row) > 1, 1)
