Query or a function to calculate balances automatically

[erickemboi]

Hello everyone. I am developing Students Fees Scheduler. Kindly, please I am requesting anyone to assist me with a QUERY or a FUNCTION to automatically calculate balances when certain amount of money has been paid. It should look like this:
TOTAL AMOUNT OF MONEY TO BE PAID- let's call it x
PAYMENT DATE-
AMOUNT PAID-
BALANCE- (TO BE SUBTRACTED FROM x)


please, fees can be paid in different dates and with different amounts
Thanks in advance.
Kindly check attached database. God bless you.

you actually need more tables,

tFeesCharged tbl:
FeeID(autonum), FeeName, studentID, FeeDate, note

tPayments tbl:
PayID(autonum),studentID, DatePd, AmtPd, FeeID


1 table the holds all fees charged to student
1 table the holds all payment made by student
then a query is run to sum each table, the difference will be balance due.

When I create the two tables, when i try to edit i get "THIS RECORDSET IS NOT UPDATEABLE"
