program wont renew total
ok so heress my code... it looks the way its supposed to (except that it shows 1 zero instead of 2 while total is 0 so any additional help with that is appreciated)... it compiles correctly... but when i click on the checkboxes, the total doesnt change which is really irritating cause once this minor problem is out of the way the code is finished...
