COUNTIFS formula not counting correctly

Hello, I'm using:

=SUM(COUNTIFS($P:$P, "Program Planning & Policy",$O:$O, {"AZ","CA","DC","IN","LA","ME","MI","NC","NY","PR","TX","VT","WA"},$S:$S, {"Reg.","IS"}))

To try an count some data, however it seem if I try to add the add the additional criteria to the last range of "IS" the formula no longer works.... If I'm just counting for "Reg." or "IS" individually it counts correctly....

Why can't I count the last range for 2 criteria... is there an alternate work around apart from doing two COUNTIFS ala:

=SUM(COUNTIFS($P:$P, "Program Planning & Policy",$S:$S, "Reg.",$O:$O, {"AZ","CA","DC","IN","LA","ME","MI","NC","NY","PR","TX","VT","WA"}),COUNTIFS($P:$P, "Program Planning & Policy",$S:$S, "IS",$O:$O, {"AZ","CA","DC","IN","LA","ME","MI","NC","NY","PR","TX","VT","WA"}))

When you have 2 multi-element criteria ranges in COUNTIFS one needs to be separated by commas and one by semi-colons (assuming UK/US regional settings), so if you change the last comma , to a semi-colon ; your original formula will work, i.e.

=SUM(COUNTIFS($P:$P, "Program Planning & Policy",$O:$O, {"AZ","CA","DC","IN","LA","ME","MI","NC","NY","PR","TX","VT","WA"},$S:$S, {"Reg.";"IS"}))

If you have 3 or more multi-element criteria you need to use something like NB_VC's suggestion

It's because the criteria arrays aren't the same size....


=SUMPRODUCT((P1:P10="Program Planning & Policy")*(ISNUMBER(MATCH(O1:O10,{"AZ","CA","DC","IN","LA","ME","MI","NC","NY","PR","TX","VT","WA"},0)))*(ISNUMBER(MATCH(S1:S10,{"Reg.","IS"},0))))

adjust ranges to suit... but do not use unnecessarily large ranges.

Hey barry,

Thanks.. you taught me something too :)

Thanks, note that even if the criteria arrays are the same size like this:


then with comma separators for both you will only count a/x, b/y and c/z combinations. To count all combinations you still need to have commas for one and semi-colons for the other like this:

Oh, I see.  Thanks again for elaborating.  When I tested I got the correct result without realizing that they were aligned as you mentioned.  :)
