I have a workbook that will have a varying number of
worksheets. The worksheet names will be "list (1)"
thru "list (xx)". Each worksheet has several cells that
that use "conditional sum" function to total quantities of
items based defined conditions.

I'd like to have a place on "list (1)" that will provide
total quantities that span all "lists", but I'm not sure
where to start.

I think I want to count the number of worksheets
named "list (*)", then, if "list (4)" exists, add the
value of the specific cell, if not, add zero. Am I on the
right track, or is there a better way? Can someone show
how to get started? Point me in the right direction and
I'll run with it.

THANKS!
Rich
