formula ?

In your formula (and mine!) is b2 a cell reference?
Not sure why yours did not work - I tried it and it seemed OK
the double negative way is generally preferred - it follows the SUMPRODUCT
syntax more closely
=SUMPRODUCT(array-A, array-B,....)

Hi Bernard,

Yes, b2 is a cell reference.
The formula always worked until a week ago, I did not change anything and
just copied the same formula to the new row.
Anyway, the double negative way works now and I'll use this syntax from now
on to avoid any sudden surprise.

Thanks again
Andy
