Hey, I need help on a scrolling thumbnail

Hey everyone, I’m new to this forum, so please be kind to me.

Anyhow, I am trying to make a scrolling horizontal thumbnail bar exactly like the one on Kirupa’s tutorials, however, I’ve gotten everything down except that it wont scroll. Can anyone help me with this? Thanks in advance.

Here is my code: ActionScript 2.0
(I am using the _root to call into movieclip holders in the main swf. I am trying to create this scrolling thumbnail bar in a loaded external swf).

for (i=0; i<_root.productname.length; i++) {
thumbnails_fn(i);
};
p = 1;
function nextImage() {
p++;
if (loaded == filesize) {
_root.imageMC.image.unloadMovie();
_root.imageMC.image._alpha = 100;
_root.ITEM = _root.productname[p-1];
_root.imageMC.image.loadMovie(“imageloader.swf”);
}
}
function thumbNailScroller() {
// thumbnail code!
this.createEmptyMovieClip(“tscroller”, 1000);
scroll_speed = 6;
tscroller.onEnterFrame = function() {
if ((_root._ymouse>=thumbnail_mc._y) && (_root._ymouse<=thumbnail_mc._y+thumbnail_mc._height)) {
if ((_root._xmouse>=(hit_right._x-40)) && (thumbnail_mc.hitTest(hit_right))) {
thumbnail_mc._x -= scroll_speed;
} else if ((_root._xmouse<=(hit_left._x+40)) && (thumbnail_mc.hitTest(hit_left))) {
thumbnail_mc._x += scroll_speed;
}
} else {
delete tscroller.onEnterFrame;
}
};
}
function thumbnails_fn(k) {
k++;
thumbnail_mc.createEmptyMovieClip(“t”+k, thumbnail_mc.getNextHighestDepth());
tlistener = new Object();
tlistener.onLoadInit = function(target_mc) {
target_mc._x = -125+((target_mc._width+5)*k);
target_mc.pictureValue = k;
target_mc.onRelease = function() {
p = this.pictureValue-1;
nextImage();
_root.shadow_mc._visible = true;
_root.shadow_mc._alpha = 40;
};
target_mc.onRollOver = function() {
this._alpha = 50;
thumbNailScroller();
};
target_mc.onRollOut = function() {
this._alpha = 100;
};
};
image_mcl = new MovieClipLoader();
image_mcl.addListener(tlistener);
thumbnaillocation = “gallery/” + _root.TYPE + “/” + _root.productname[k-1] + “/showcase/1.png”;
image_mcl.loadClip(thumbnaillocation, “thumbnail_mc.t”+k);
}
