Flash CS3 (AS2) XML scrolling gallery help

programming flash
1

Hello all,
I’m making a scrolling gallery with videos and thumbnails loaded from XML. The gallery works but I can’t for the life of me figure out how to make the following thing happen:

[LIST]The selected thumbnail stay highlighted while the current video is playing[/LIST]

[LIST]Once the video is done playing, the thumbnail changes color. [/LIST]

Any help would be greatly appreciated. Here’s the thumbnail-specific code:

function thumbNailScroller() {
	this.createEmptyMovieClip("tscroller",1000);


	this.onEnterFrame = function() {

		if ((_xmouse>=(hit_right._x)) && (thumbnail_mc.hitTest(hit_right))) {
			thumbnail_mc._x -= scroll_speed;


		} else if ((_xmouse<=(hit_left._x)) && (thumbnail_mc.hitTest(hit_left))) {
			thumbnail_mc._x += scroll_speed;


		}
	};
}





function thumbnails_fn(k) {
	thumbnail_mc.createEmptyMovieClip("t"+k,thumbnail_mc.getNextHighestDepth());

	tlistener = new Object();
	tlistener.onLoadInit = function(target_mc) {
		target_mc._x = hit_left._x+(target_mc._width+5)*k;
		target_mc.pictureValue = k;
		target_mc.onRelease = function() {
			target_mc.filters = [gf];
			pausePlay.gotoAndStop(1);
			netStream.play(clip[k],1);
			playVid = true;
			texty.desc_txt.text = " ";
			texty._alpha = 0;
			p = this.pictureValue;
			this._alpha = 0;
			var colorTrans:ColorTransform = new ColorTransform();
			colorTrans.redOffset = -130;
			colorTrans.greenOffset = -80;
			colorTrans.blueOffset = 0;
			var trans:Transform = new Transform(this);
			trans.colorTransform = colorTrans;
			target_mc.filters = [];
		};
		



		target_mc.onRollOver = function() {
			texty._alpha = 100;
			texty._x = _xmouse;
			texty.desc_txt.text = description[k];
			target_mc.filters = [gf];
		};


		target_mc.onRollOut = function() {
			texty.desc_txt.text = " ";
			texty._alpha = 0;
			target_mc.filters = [];
		};
	};

	image_mcl = new MovieClipLoader();
	image_mcl.addListener(tlistener);
	image_mcl.loadClip(thumbnails[k],"thumbnail_mc.t"+k);

}
