Hi all,

I have 3 MCs (my\_mc0, my\_mc1 and my\_mc2) on my stage. And I need to apply the same motion tween on them.  
So, follow the script that I’ve tried to do it:

```auto

import fl.transitions.Tween;
import fl.transitions.easing.*;
import fl.transitions.TweenEvent; 

var nav_array:Array = new Array("Home", "About", "Info");

for (var i:int=0; i<nav_array.length; i++) {
    var objeto = this["my_mc"+i];
    objeto.navText.text = nav_array*;
    var efeito = "x";
    var anima = Strong.easeInOut;
    var pos_ini = objeto.x;
    var pos_fin = objeto.x+200;
    }
    var myTween = new Tween(objeto, efeito, anima, pos_ini,pos_fin, 1, true);
    myTween.stop(); 
    
    objeto.addEventListener(MouseEvent.CLICK, onClick);
    
    function onClick(e:MouseEvent):void {
        myTween.start();
        trace(objeto.name);
    }

```

However, only the last MC (my\_mc2) is working properly (when I click on it, the motion tween runs). Moreover, the output window only displays “my\_mc2”, and disregards the other MovieClips.

What is wrong in my code?

Thanks for any help!
