Pls help: random motion source file won't open in mx

hi me again, more random problems!

basically i’m trying to get to grips with random motion:
this is my current script//

createEmptyMovieClip(“paper”, 5);
mc.setMask(paper);
for (var i = 0; i<20; i++) {
myClip = paper.attachMovie(“c”, “c”+i, i);
myClip._x = Math.round(Math.random()*350);
myClip._y = Math.round(Math.random()*350)+20;
myClip.velX = Math.round(Math.random()*10)-5;
myClip.velY = Math.round(Math.random()*20)-5;
myClip.onEnterFrame = wobble;
}
function wobble() {
this._x += this.velX;
this._y += this.velY;
if (this._x<0 || this._x>0) {
this.velX *= -1;
}
if (this._y<10 || this._y>380) {
this.velY *= -1;
}
}

//all i want is for the x movement to be random, i’ve been trying to modify the code by taking out some of the y math.random / math.round bits…

pls can someone help me on the right track :rabbit:

ps: by the way i have been trying to open the tutorial file “four.fla” but it won’t let me open in flash mx… can anyone verify. pls. the force is weak today : )
