Global Variables and Local Variables.

[JoeBradleyUK]

Ok, the responses have made it a little better to understand, I don't know why but I can't seem to understand them fully! I understand the concept, it's just the actual scripting, say if I wanted a script area to only work once I have done something, would I make it so the set variable is 1 and when you go into the area it adds 1 which would activate that area? Is it kind of like that? Or am I wrong?
