[hamsterman]

does it work?
if not, post the errors
if yes, whats the problem?

you could at least say what are you trying to do and what libraries are you using,
and use [code] tags and some proper indentation too, and why the ">" ?
also, use arrays for god's sake (arrays combined with for loops)

Oh I agree, this unfortunately doesn't help anyone help you.

If u need an example of how to ask then check out "For Loop Problem" that i posted yesterday in the beginners forum.

It even has an example of Array and For statments.
