Ahh I see now.

Thanks again Kalle/Tanax...

Since the return is "true".

Then it just returns the number that you are checking right?

so say 5 is a good number, then you get 5 back?

Since PHP is loosely typed, do you have to do "return false" if the number doesn't check out?

It sounds like good practice to do that anyways, but just wondering.
