Why isn't my sword fighting mainscript not working properly?

So in this MainScript, I'm experiencing some issues. I looked at the output and everything seems fine, but when I tested it out, things weren't working. The game wasn't function properly. 2 players joined in, and they were getting teleported in and out of the lobby to the map in a short time and the GUI was announcing people winning in a matter of seconds. No one was even fighting or killing.

Thanks in advance!

Below is a server script inside ServerScriptStorage, named "MainScript"
