How come this doesn't work?

onClipEvent(load){
this.attachMovie(“haupp_mc1”,“haupp_mc”,this.getNextHighestDepth());
haupp_mc._xscale=0
haupp_mc._yscale=0
}

onClipEvent(enterFrame){
if (this.mouseOver() == true) {
haupp_mc._xscale+=50
haupp_mc._yscale+=50
}
}

The mouseOver event doesn’t work should be pretty basic but…
y’know it’s flash and that which should be simple is usually a PIA
