I did that from your previous response. I'll give you an example of whats happening:

GROUP HEADER BAND
Acct# 201 John Doe


DETAIL BAND
Invoice# 1000 1.00
Invoice# 1001 1.00
Invoice# 1002 1.00


GROUP FOOTER BAND
Acct Balance 3.00

The account balance value comes from a variable(nCusBalance) set up in the report variables. The value of the variable is a call to the calculate balance function. It is set to reset at the end of the group.


SUMMARY
Total Balance 9.00

The total balance value comes from another variable(nTotCusBalance) set up in the report variables. The value of this variable is nCusBalance. The calculation is sum. And is set to reset at the end of the report.

Notice that the total balance is the total balance multiplied by the number of detail records.

Any Ideas?
