and start over. There is more than 1 thing in your code that needs to be changed. Please ask a semi-specific question; since this is apparently a school assignment, we probably shouldn't just give you "working code".
edit: you can add me on skype if you have more than a couple questions / need things explained. Username is same as here at mpgh.
