I am using a workbook which contains 3 sheets representing a country(Mexico,
Brazil, India) .In these sheets there are 4 columns which contain the
following:

(Customer Name) (Customer Account) (Dollar Amt) (Product Id)

There are multiple Product Id that can be charged to a customer account and
i am using a filter by product id to get sum amount of customers from each
country.How does one get a sum for all countrys combined?

Thanks
