Help! how to remove a movie effect for other scene

Question

Hi I am working on an e-card. I have 2 scene where "Scene 1"
has snow fall effect and "Scene 2" has message and greetings but do
not want the snow fall effect. So far the snow effect run through
out both scene but I need to stop it on scene 2.
The script that i got online is put under frame-script at
Scene 1. How can i make it stop at scene 2 and when the movie loop
back to scene 1 , the snow effect will run again?
Please help. thanks a lot.
Below are the script that i got from a tutorial to create
snow effect. It is put under scene 1 first frame.

rap onEnterframe with if statement testing what scene you are
in if not scene one animation stops. or put snow animation in its
own movie clip.
this.onEnterFrame = function() {
if(scene == 1){
for(var i=0;i<anzahl;i++) {
if(this["schnee"+i]._x>breite+10||this["schnee"+i]._y>hoehe+10
|| ersterlauf<anzahl) {
this["schnee"+i].speed =
(Math.random()*max_speed)+min_speed;
this["schnee"+i]._x = Math.random()*breite;
this["schnee"+i]._y = ersterlauf<anzahl ?
Math.random()*hoehe : 0;
this["schnee"+i]._xscale = this["schnee"+i]._yscale =
this["schnee"+i]._alpha = (Math.random()*max_groesse)+min_groesse;;
this["schnee"+i].r_xy = random(2) == true;
ersterlauf<anzahl ? ersterlauf++ : ersterlauf = anzahl+1;
} else {
if(this["schnee"+i].r_xy) {
this["schnee"+i].go += Math.random()*-0.2;
if(this["schnee"+i].go < -schwing_faktor)
this["schnee"+i].r_xy = false;
} else {
this["schnee"+i].go += Math.random()*0.2;
if(this["schnee"+i].go > schwing_faktor)
this["schnee"+i].r_xy = true;
this["schnee"+i]._x += this["schnee"+i].go;
this["schnee"+i]._y += this["schnee"+i].speed;
something like this.
