Why is my Teamchanging/Teleportation loop malfunctioning?

This is the main script for my first game project. Everything works fine up until the changing teams and teleportation/section. When play testing in a local server everything seems to be in order, however when I bring a friend in to test in play mode only I am teleported and teamchanged. Thank you for your help! :)))
