PA,
You'll need to add a Grouping to your report based on Customer (ex. CustID).
(use the report Sorting and Grouping dialog box)
In that Sorting and Grouping dialog, create a Customer Header and Footer, and
place the CustID and the CustName field in that Header.
In the Detail section of the report place all your Invoice data. (ex. InvNo and InvAmt)
In the CUSTOMER footer, an unbound text control with = Sum(InvAmt) would yield the
totals for each customer.
In the REPORT footer = Sum(InvAmt) would yield the totals for ALL customers.

Thank you for the help. Worked very well, and given that as a starting
point, was able to go much further.
