Not really sure whats up

[slimjim]

Well not really sure whats up. Heres the problem. IF one person uses the exit exchange code. And in the window that pops up if that member is using the exit exchange code and so on.
I get like an infinate loop or something happening that does not stop.

I have beat my self in the head over this and even had someone look at it for me. SO i am hoping someone here sees the problem.
