Hello!
Can someone please advise what am I doing wrong getting this error?
The formula used is as follows:
=COUNTIFS({ref sheet}, AND(MONTH(@cell) = 1, YEAR(@cell) = 2021))
The date column in the reference sheet is set as "Date" and the format is DD-Mon-YYYY (e.g. 19-Jan-2021). I've tried creating a default date column in my metrics sheet too, however, it made no change.
Any help is appreciated!
