Number of cells that have same values

[Lingyan Hu]

Imagine there are two columns of cells, each row of two cells are
corresponding to each other. How to find out the number of rows where the two
corresponding cells have the same value?

[David Billigmeier]

Assume your Columns are A and B, and your rows go down to 20, Array enter
this formula (CTRL+SHIFT+ENTER):

=SUM(IF(A1:A20=B1:B20,1,0))

Change the column and row references to fit your data.

=SUMPRODUCT(--(A2:A20=B2:B20),--(A2:A20<>""),--(B2:B20<>""))

Shall I push (CTRL+SHIFT+ENTER) at the same time while entering the formula?
I tried, but it doesn't seem to work.

Type this formula in the formula bar, and instead of just pushing "Enter" to
commit it, push CTRL+SHIFT+ENTER.

Also, after looking at Bob's post I realize my formula isn't taking into
account blank cells, change to the following to fix (or just use Bob's
formula):

=SUM(IF(((A1:A20=B1:B20)*(A1:A20<>"")*(B1:B20<>"")),1,0))

Dave,

Your version can do away with the IF test

=SUM(((A1:A20=B1:B20)*(A1:A20<>"")*(B1:B20<>"")))

Very true, there are many ways to word it.
