Hi - I need a formula that can look at a Member Number (Column A) and report back if location (Column B) matches 1 of 6 locations, then looks to the date of occurance (Column N) but only adds back 1 value of repeating dates.
I have this, but it is not coming back with the right answer...
=SUMPRODUCT(('2017'!I$3:I$10000=$A223)*ISNUMBER(SEARCH({"2","6","58","69","76","97"},'2017'!N$3:N$10000)))
Information is corporate private, so I won't be uploading file.
