Hi Andy

one way
=SUMPRODUCT(--(LEFT($A$1:$A$100="AB"),--($B$1:$B$100="Pass"))
Change ranges to suit but ensure that they are of equal length.

I want to count the number of "passes" from a column based on the
criteria that the adjacent column cells contain the letters "AB" at the
start of what ever is in the cell.

i.e.

column A column B
AB xxx pass
AB yyy pass
BC zzz pass
BC xxx fail
AB yyy fail

etc

Any ideas

thanks
