I receive a template every month where subtotals are by customer (rows of
data to be summed are different each month). I need to add three columns each
month and be able to sum by each subtotaled line without any data in the
lines above the subtotal as the sales person will input the amounts
(forecasting). Any suggestions?

So is it like this?

Customer A xxxxx
xxxxx
xxxxx
A Subtotal: nnnnn
-----------
Customer B xxxxx
xxxxx
xxxxx
B Subtotal: nnnnn
-------------

If so, sum the entire column and divide by 2, just make sure that all
customers have a subtotal. This will give you the grand total.

I don't understand the purpose of your three new columns, can you
elaborate?
