Touched Part only works for the latest player that joins?

So, I've been working on a game with some friends and we're trying to do something simple. But there is an issue with the selling part of the game. If your in a solo server it works just fine, but in multiplayer server, whenever you hit the sell part it only sells the latest person that joins items. This is a pretty big issue here, and i would appreciate it if someone could look at my code and maybe make a few tweaks.

The most important part is between lines 49 and 66.
