Animate instance of a movieClip

1

Hey,
Im new to this forum and to AS3. I was wondering if some of you could point me in the right direction for a problem i’ve been strugling with for some time.
I’ve been looking trought forums and tuturials but cant seem to find the right answer.

In this example i created 3 movieclips and added 10textFields into it.After this i want to be able to let these 3 movieclips tween…
Atleast this is what i want but i cant seem to get it right.



import flash.display.MovieClip;
import fl.transitions.Tween;
import fl.transitions.easing.*;

 for (var b:Number = 0; b < 3; b++){
        var mc:MovieClip = new MovieClip();   
        mc.name = "mClip" + b;
        mc.graphics.beginFill(0xCCCCCC);  
        mc.graphics.drawRect( 10 * b, 30 * b, 50, 50 );  
        mc.graphics.endFill();  

                for (var i:Number = 0; i<10; i++)
                {
                    var tf:TextField = new TextField;
                    tf.name = "tf" + i;
                    tf.textColor = 0xA5C71B;
                    tf.x = i * 5;
                    tf.y = i* 10;
                    tf.text = "text" + i;
                    addChild(tf);
                    mc.addChildAt(tf,i);
                 }
            parent.getChildByName("mClip" + b);

 var TweenX:Tween = new Tween(mc, "x", Strong.easeOut, 200,5,5,true);
    
                stage.addChildAt(mc,b); 
    
}
