How to make this work on 2 machines?

Hey guys, I got this multiplayer script and i got player 1 and 2 to work on my machine, so how do you make it work on 2 different computers?

Player 1

Player 2

Is this what i think it is?
Are you saving positions and loading them???/
or is it my component…

Im pretty sure that that is not online, it simply saves to a file.
