Thanks Rik! That seemed to have done the trick... What exactly do the {
} do? Is there a good online reference you know about that I could
learn some more? The few sites I've found are very vague on how
variables work.. like strings integers, arrays etc.. I'm used to C++ so
if I could find a comprehensive site that'd be great. Thanks again for
your help Rik, you're a life saver!
