Hello All,
Can someone help me figure out why this formula is not working anymore?
=COUNTIFS({OSPO Engagements Archive complete date}, IFERROR(MONTH(@cell), 0) = 1, {OSPO Engagements Archive Hierarchy}, =0, {OSPO Engagements Archive complete date}, IFERROR(YEAR(@cell), 0) = 2019)
It used to count all of the rows for a specific month and year where the hierarchy was "0". It is now returning "Incorrect Argument".
