addChild and instance name

programming flash

Hi,
I am trying to dynamically add a child to stage, this works. Then I try to access it using the instance name and I can’t. Why can’t I do this?


intro_btn.addEventListener(MouseEvent.CLICK, goIntro);

function goIntro(EVENT){
    var intro:MovieClip;
    intro = new Intro();
    intro.name = "scr";
    targetX_mc.addChild(intro);
    targetX_mc.scr.sb.init(targetX_mc.scr.txt_mc, "easeOutBack",2,true,2);
}

Thank you,
Kim
