Kiosk touchscreen (URGENT)

1

hi, hope someone can help me.
well im creating a touchscreen application, i have this code:

System.useCodepage = true;Stage.scaleMode = "noscale";
import com.mosesSupposes.fuse.*;
ZigoEngine.register(Fuse, FuseItem, FuseFMP, PennerEasing);

MovieClip.prototype.bt = function(){
     this.onRollOver = function(){        ZigoEngine.doTween({target:this, scale:150, ease:'easeOutQuint', seconds[IMG]http://flashden.net/images/smileys/surprised.gif[/IMG].8});
        this.swapDepths(1000)
    }
      this.onRollOut = function(){
        ZigoEngine.doTween({target:this, scale:100, ease:'easeOutQuint', seconds[IMG]http://flashden.net/images/smileys/surprised.gif[/IMG].8});
    }
}

setup = function(){
    for (var i:Number = 0; i<82; i++){
        this["f"+(i+1)].bt();
    }
}
setup();

well this is my code, what it does is that i have 82 squares in the movie when i roll over any of them then they scale to 150% and when i roll out they scale to 100%
when when i try this to touchscreen i found that the rollover and rollout dont work in touch screen i have try with dragover and dragout and i dont found anything
can someone help me to solve this ??
