Xscale problem

1

I’ve just got a simple mc on stage of a rectangle.
I want the clip to go from its full width, then scale down to nothing and stop.


onClipEvent(enterFrame) {
this._xscale-=5;
}

The above code starts what I want, but I don’t want it to continue into the negative.(if that makes sense)
So I came up with this but its not working:


onClipEvent(load){
	origWidth = this._width
}
onClipEvent(enterFrame) {
	if(origWidth>=126) {
		this._xscale-=5;
	}else if (origWidth<=0) {
		delete this.onEnterFrame;
	}
}

I’m probably making this more complicated than it should be.
Oh, and ‘126’ is the actual width of the clip in the properties inspector.
Thanks
