Im a bit confused on how to use a proximity prompt in scripting. Help?

I am using a proximity prompt to trigger a shop menu in the game. the gui does work and everyhing. its just that my script doesn't work. i have tried using the

game.part.proximityPrompt.triggered:connect(function(player)

but that makes a function that doesn't do any thing. even if you put a simple script in it. Help!
