How to go from the bottom of your script back to the top in game?

I just want to know how to get from the bottom of my script back to the top so i can replay my three i tweens, because i cant loop them

Um ... weird question ... but I think what you should probably do is have your tweens in a method that you can call. Then, if you want to have the code executed again, just call the method again. It'll probably be a Coroutine, so you may have to use StartCoroutine in order to do that.
