creamte og attache i en class?

Hvorfor attacher den ikke rigtigt noget.

class Attach extends MovieClip...

    var ClipName:String;
    var ClipGraphics:String;
    var ClipDepth:Number;

    function Attach (clip_name:String, clip_graphics:String, depth:Number, x:Number, y:Number, width:Number, height:Number) {
        ClipName = clip_name;
        this.createEmptyMovieClip (clip_name, depth);
        this[clip_name].moveto (x, y);
        this[clip_name].attachMovie (clip_graphics, depth);
        this.setWidth (width, height);
        this.setClipPos (x, y);
    }
   
Og så..

var test:Clip = new Clip("clip1","graphics2",10,100,150,400,300);
