This is a part of a script on Roblox wiki, Saving Player Data. I've tried altering it in all sorts of ways but i just can't figure anything out. I've made an obby and a leaderboard that tracks 2 things.The level you've reached and a number of trophies you've collected, and that's the information that's i need saved when a player leaves(i also need it to teleport the player to a checkpoint of a level,based on this info, but i'd be happy with just getting it to remember the numbers) Most of the script is already done i just don't understand what variables i need to add to make it work for my game.

Thanks for your time
