The specific error says "Run-Time Check Faliure #2 stack around the variable 'amount' was corrupted." I tired checking over my code but i don't notice anything wrong. This didn't happen before I added my comments. Can anyone help me out? I know the code is kinda long but any help would be appriciated!
