Charlotte,

This would be a simple list of the names of the sheets that the counting is
to affect, in a column say, and then given a workbook name
(InsertNameDefine Name...) of Sheets. This will then present an array to
SUMPRODUCT that it can work on, one by one effectively.

where Sheets is a named list of the sheets to count over, and it is an
array formula, so commit with Ctrl-Shift-Enter.


I was trying this solution, but I confess having no idea to form a "named
list of sheets".

Could you pls. give a hint?

Thanks,
