Sorry, the forumula I'm using is without the second SUMPRODUCT

ie SUMPRODUCT(B1:B39=1)*SUMPRODUCT(C1:C39=1)
ETC

I have a spreadsheet where I have 2 columns of numbers and am trying to use
SUMPRODUCT count paired cominations. Each person has a score Rating & Score
of 1, 2, 3 or 4

The database looks like this:
Name Rating Score
Fred Bloggs 1 2
Jo Evans 4 3
Anne Smtih 2 2
Jane Oliver 1 2
etc

The formula I am to count each of the 16 possible combinations is:

SUMPRODUCT(B1:B36=1)*SUMPRODUCT(C1:C36=1)
SUMPRODUCT(B1:B36=1)*SUMPRODUCT(C1:C36=1)
etc

However, I get a 0 return. I use the same formula on a database that uses
letters rather than numbers and this works fine, so I'm presuming it's
because this one uses numbers. I have tried formatting the cells for
general, text and numbers and nothing seems to change the result.

Any ideas?

Many thanks.
