How to make a respawn system?

Hi everyone!
I am trying to make a spawn system (in a rolling ball game) so that when you fall of the platform (there is a trigger box underneath) the ball will respawn on the last checkpoint.
the fact is tahat I made some kind of respawn platforms and when i get pass one, the next time I press R it will spawn me on the last platform I have passed. It only works with the R button but I can not seem to make it work when the ball hit the triggerbox underneath

Hey there,

would you mind showing me your R - Button code and the Triggerbox code?

Also, do you have any errors popping up? Or any other information that could help fixing this for you?

(: Cheers!

Q is the ball and the triggerBox is just a box collision
