Or you can do it in VBA and use a for each loop

for each ws in activeworkbook.worksheets
total = total + ws.cells(row,col).value
next

or something like that.
-----Original Message-----
if you are summing information across sheets and the
information is in the
same cell on each sheet, put in a sheet named Start and
a sheet named End.
Put all sheets to be summarized between these two sheets.

In the summary sheet use a 3D formula

=Sum(Start:End!A1)

as an example.

All sheets between Start and End will be included in the
sum (start and
end should be blank sheets.)

The number of sheets in my workbook varies from day to
day, with unique
names for each sheet. I am trying to total cell
contents from those sheets
on a summary sheet. There is a cell whose contents are
common to the sheet
name. I am at a complete loss as to where to begin.
There is not a lot of
information here but I am not sure how to post enough to
help. Remove nospam
to respond via email
Thanks in advance
Steve
