C# problem I cant get this cash register to work correctly HELP!?
You need to say what the problem is, what you've done to try to fix it, and any information about other methods you tried. Don't just post your code and ask us to fix it... that's your job. You need to give some indication that you've tried to narrow down the problem to something more specific than "the entire program"
