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 🐇
