Some problem to do with looping...

[DizzyDoo]

Hi, I'm attempting to make an online Platform engine, with the platform tutorial from the downloads page. At the moment all I have is a system that lets you connect and when you press A jump, and send a message saying "jump" to other computers. This works, but only with 2 people. I seem to get odd results with 3 or more. I'm sure this is too do with the way I am looping things, and would be extremely thankful if someone could fix this up for me. I've tried a few things but none of them work.

Here is the file:

Please note there is no left/right movement yet :P thats too come. Anyhelp at all is much appreciated.

Bumped because it's on the third page, and no one will look at it <_<.
