Add Highscore to Platform game

I created a classic platform game. I added a highscore by choosing "add global variable". But now when the charakter reaches the finish line the game must end somehow. I?d like to create a final score that pops out as soon as my character touches the finish line. Please help me! The most important thing is that the game has to end somehow by showing the final score.

1.- Make the score invisible from the start (hint: use a hidden layout)

2.- Trigger visibility when the user reaches finish line.

3.- remember to turn off character movement too.

free tip: hidden buttons must be disabled when hidden!
