First off: as i said in the other thread already, if this is homework or classwork you need to post in the special forum part : Homework & Coursework Questions.

Second: if you have tried code and it doesn't work - post it here, however buggy. How are we supposed to tell you what you did wrong if we can't see what you did?

And, finally: please do post multiple times just because you don't get an immediate answer. We are volunteers here, this is not a paid helpdesk. It is not unusual to wait a day for an answer. If you need immediate, responsible help please pay a professional to work for you.

And this is funny, because actually you are posting here.

I hope this helps.
