I have the following equation I am trying to get working: =COUNTIFS({Range 1}, =1, {Range 2}, IFERROR(YEAR(@cell), 0) = 2018, {Range 2}, IFERROR(MONTH(@cell), 0) = January, {Range 3}, OR(@Cell="", @Cell="")) The equation has worked in the past without the or statement at the end. It was once looking for one value here, now I want it to look for multiples. Is this possible?
