Can you post your formula, so we can see what you're working with?

Is there a limit on the number of rows that can be referenced in a
SUMPRODUCT's array reference? When I try to reference arrays with ~2200
rows the formular no longer works. My sumproduct formular is using two
criteria arrays and one array of results to sum.

Thanks for any help that can be offer.
