I found this equation on contextures.com after the post, what is the
difference? They both seem to work properly.

=SUMPRODUCT(--($F$8:$F$207=12),--(I8:I207="x"))

Thanks

Maybe

=SUMPRODUCT((A1:A19=12)*(B1:B19="X"))

I have two columns, one has variable data while the other is x/empty.
I am
trying to count the number of "x" for a certain variable. Below is an
example of the set up:

Size Replace
12 x
12
12 x
18 x
18 x
18 x
24
24
24 x

The formula cells would equate to the total column below:

Size Total
12 2
18 3
24 1

Any help would be great, Thanks
