u may also try to take advantage of a Spinner from the Form tools (format
control with min(1), max(12)) to toggle a cell, let say B1 which is the
Spinners Cell link.

then your formula remains something like this for toggling results.
=SUMPRODUCT(--(Region=E$11),--(Group=$D17),B1)

Hi to all,

I am trying to build a basic Balance Sheet to use as a reference for another
project. One worksheet contains all the data for each month of 2006 (monthly
ending balances), and I am using the following to pull it into my template:

=SUMPRODUCT(--(Region=E$11),--(Group=$D17),January)

Where Region is the region the office is in, Group is the account group the
balance belongs to (Cash, A/R etc.) and January is the month to show (all
ranges are named).

Is there a way I can setup some form of toggle for the month , so I can
switch between each of the 12 months, and not have to change formulae or
create duplicate worksheets? All help appreciated.

Regards,

Alan
