Problem with save function

So I made this code to save the players location, and then load it when the player rejoins the game. However, for some reason it is not working. It looks fine from everything that I see. Help please.

You need to read before you can save, make a switch that turns on after the Once.

@“JR 01” i dont know how to use switch sadly, could you make an example? game link is: http://flowlab.io/game/view/1407935
sorry for the trouble

You can do it like this, but probably doesn’t help of the rocks are random every time you play it.
