Running Balance on a form

S

2000

How can I make a running balance of a form that looks something like this:

Date Charge Payment Balance
01/02/04 12.00 12.00
01/07/04 5.00 7.00


Do I have to store the balance in the Customer record and then retrive it
for a transaction and then write it back to the customer record.?

Thanks.
