A timing event (like wait or every x seconds) doesn't work in a loop. A loop will be completed in 1. tick. So your 'every 1 second' will never happend. If you want to address to all instances you doesn't need a loop over all instances at all.
I would do it like that:

If you wonder what 'Set position' do, try to disable it and put your player on a platform.
