print("On server")
return require(408470686)
end
Local Script

I have asked this a thousand times and no-one can answer it with a working solution. It's only 5 lines, and that's it. This is all the code I have in my game. Nothing prints in the server or client output.

... What does the module with the id (408470686) return? Just take the module and put it in your game - It's not hard.
