Speedrun Timer

Hello, I’m trying to create a game with a speedrun timer, but I can’t figure out how to make the timer stop on the last level.
Here’s my game: https://flowlab.io/game/view/1340711
Sorry for the cluttered behaviors.

Umm Im Not Good With Speed Runs But Maybe @“JR 01” Can Help He’s Really Good At Timers

You want to stamp the time when you get a bone, you you need a switch that turns itself off to get a once output from the timer. This will make a stamp for when you beat the game.
