Adding A Script To A Scene

Hello I recently created the script below. function Update(){ if(Input.touchCount > 1){ Application.LoadLevel("1"); } } My question is how would I attach this to an object or anything to make the scene change. I don't really care what I have to touch to advance to the next scene ( The game is still in very early stages and I just want some basic scenes to be able to switch). Thanks a ton in advance any help would be greatly appreciated.
