Needing help with character hitting object that plays sound but loops if stuck on object (with do once added)

I have marked this as resolved, massive thanks ClockworkOcen. As this allowed me to have when the character hits the bars it would play every time. Though a little bug that I can’t figure out (but will leave it for now, or just leave it) is when the character gets stuck on a bar the sound plays due to the way it’s setup but it’s not a huge issue as players will reset when this happens anyways.
