Paths... _parent

I found this great fla file I want to use.

The AS path is _parent. See the code from the track (on the main timeline) guiding the scrollbar below:

onClipEvent(mouseDown) {
	if (hitTest(_root.container._xmouse, _root.container._ymouse)) {//test to see if the user has clicked on the scroll track
		if (_ymouse + this._y > _parent.scroll_bar._y + (_parent.scroll_bar._height/2)) {//if where the user has clicked in above the scroll bar, and if so
			_parent.scroll_bar._y += _parent.scroll_bar.largeChange;//move the scroll bar up
		} else {//or if the user click on the scroll track, below the scroll bar, then
			_parent.scroll_bar._y -= _parent.scroll_bar.largeChange;// move the scroll bar down
		}
	}
}
onClipEvent(load) {
	this._visible = false; //hide the track
}

Other instances use _root. I am loading this swf into my main swf. The name of the emptyMC is ‘container’. So I changed _root to _root.container. Everything controlled by the _root function - the up/down arrows work great. But the actual scrollbar, using the _parent path do not.

I have tried _this, and just removing _parent alltogether. I also tried _root_container but to no avail.

I cannot seem to find what _parent is refrencing (IIRC, _parent targets the timeline above it, but the code is ON the main timeline).

Any ideas? :sen:
