Help with stoping a action script?

I am very new to flash (5 days)! I used the snow falling action script from this website in scene five of my movie. I want the snow to stop falling at the end of scene 5 (after the snow man spins into a larger one)but it doesn’t? Any help would be greatly appriciated! Attached is my FLA if you want to take a look…Thanks again, DoOoD:hr:
