i have data for client billing. if a denial is recieved a payment amount of 0 is entered and a code(ZZ12) is place in type field. I created a report in crystal that shows me  all transactions for any client who has had at least one zz12 in the type field and a payment has also posted for the same visit. however i only want to see the group if the zz12 code was posted before the payment. As of now i see it if a payment was recieved before or after the code was entered:

that worked...thank you so much.
