Controlling Instanced MovieClip timelilne from another .as file

Question

Hi, I'm working on building a 'cover flow' similar to the scroll through iTunes uses for it's album covers.  The only difference is my 'cover' needs a background MovieClip that will sit behind it and animate when teh images are scrolled to get it a 3D effect.
So I have a MovieClip i'm exporting called coverflowItem.  This is the movie clip that will sit behind each 'cover' image and have the timeline i want to control from a different .as file.  That file is called coverflow.as where all of the elements are assembled and animated.  What i need to do now is find out how to control each instanced coverflowItem so when the arrow buttons are clicked, not only do the covers slide to the appropriate side which they are currently doing now, but also have the associated MovieClip play giving the 3D illusion.
I can call the functions from the coverflowItem.as in the coverflow.as but have had no luck actually getting the movie clips to play properly.
//Create CoverflowItem
var cover:CoverflowItem=new CoverflowItem(_data);
this code lets me assess the functions but not actually manipulate the MovieClip.  I'm sure my logic if flawed. I'm new to working with packages so any help would be appreciated!

Answer 1

if you call it from a timeline you can pass a display list item (var whatever:MyGlobal=new MyGlobal(this) ) to the constructor and assuming you're trying to reference the parent of that timeline, use:
package
    import flash.display.MovieClip;
    public class MyGlobal extends MovieClip
        public static var _dolares:Number = 3500;
        public static var _visitantes:Number;
        public static var _retroalimentacion:String = "Info box"
        //objects
        public static var _senal:Number = 0;
        public static var _flores:Number = 0;
private var dlObj:MovieClip;
        //my function
public function MyGlobal(mc:MovieClip){
dlObj=mc;
        public function decision(valor, visitantes, mensaje, irAbra, irDibujo)
            if (MyGlobal._dolares >= valor)
                //spend money
                MyGlobal._dolares -=  valor;
                //visitor effect
                MyGlobal._senal = visitantes;
                //message for info box.
                MyGlobal._retroalimentacion = mensaje;
                //show info box
                MovieClip(dlObj.root).gotoAndPlay(2);
                //////close menu ;
                MovieClip(dlObj.parent).objetoAbra.gotoAndStop(irAbra);
                //Set graphic;
                MovieClip(dlObj.parent).objetoDibujo.gotoAndStop(irDibujo);
