Scrolling pic thumbnails?

Question

Ok I hope someone can or would help  me with a actionscript3.0 dilemma. I found this great tutorial on how to create a scrolling picture thumbnail in Flash. I am currently using Flash CS4 and i am using actionscript3.0. The script below is what the tutorials says I should use
_root.onEnterFrame = function(){
if(_root._xmouse<600){
        myVar=false;
        if(_root._xmouse>600){
        myVar=true;
    if(_root._ymouse<50 and myVar==true){
        imgBar.prevFrame();
        imgBar.prevFrame();
    } else{
        imgBar.play();
        if(_root._ymouse<1220 and myVar==true){
        imgBar.prevFrame();
        imgBar.prevFrame();
    } else{
        imgBar.play();
    if(_root._xmouse>50 and _root._xmouse<600 and myVar==true);
        imgBar.stop();
I would like to control the image bar with the mouse x,y coordinates. I also noticed that the _root is no longer used with actionscript is this a correct assumption? Any help would greatly be appreciated.

Yes, _root is no longer supported, and in many cases it is an overused crutch.  You may be able to just ignore including its AS3 counterpart.  In AS3, all events are dealt with using event listener/handler function pairs.  So for the case of the onEnterFrame code, you would need to have an event listener/handler pair...
function handleEF(evt:Event):void {
// all the rest of your code
stage.addEventListener(Event.ENTER_FRAME, handleEF);
As for the rest of your code, the only thing that stands out immediately is the use of _xmouse and _ymouse.  In AS3, that would be mouseX and mouseY.
So see what you can finagle with this information and try to figure out why it doesn't work if it doesn't.
