Help syncing three jit.playlist

Hello,

Im very new with Max, and i desperately need help with a patch.

Ive gotten this patch to drag and drop, loop, drag to corners and synchronize three videos simultaneously, but it goes out of sync the whole time. I need to either automate the toggle to turn off and on after a certain amount of time, so all three videos start at the same time an then restarts after i.e. seven minutes. Or i need to alter the code so it synchronizes in another way.

Is anybody here able to help?
