[FMX2004] Movie Clip Scripting issues

I just finished doing the Falling Snow tutorial on this site, and it works…My issue is::

HOW DO I GET THE SNOW TO STOP?

I want it to play through the first scene, but when I get to Scene 2 it is still going…Any suggestions? If it’s a simple stop action, where do I put it?

Any help would be great thanks.
