If you have a blank worksheet named "first" and one named "last" and
position these so that they encompass the sheets you want to sum from
like a sandwich, they you can have a formula like:

=SUM(first:last!A1)

This will add all the A1 cells between and including those sheets. You
can move sheets into and out of the "sandwich" to model the effects of
these changes, and the formula remains the same.

Hope this helps.

Hi -
I know how to sum fields of various worksheets. *However, can I set the
formula so that if a new worksheet is added, the formula will automatically
update to include the new worksheet? *(Data in the same cell as other
worksheets.)

Thank you!!
