Told you the wrong thing, sorry.
Now that you have a prog that works, try to post only a relevant section of code, not the whole program. It'll make it easier for people to read and understand what you mean when you ask questions. If you or someone else thinks the whole prog is needed, then by all means, post it, but only if necessary.
Im just not sure where to put the print staements, this is what I have come up with:
