As3 (Flash CS4) Actionscript array/mc display order

Question

Hi there,
Im trying to amend this actionsscript so the rollover part appears above the image gallery. Ive tried everything i can think of and the rollover appears below the images.
If anyone can help I would be eternally grateful!
Here is the actionscript...

Anyone got any odeas on how I can get this to work?
Looking at the code this part is the part which i need to appear on top of everything else.
function tn_over(e:MouseEvent):void
    var mc:MovieClip =  MovieClip(e.target);
    var s_no:Number =  parseInt(mc.name.slice(8,10));
     thumbnail_group.addChild(mc);
    new Tween(mc, "scaleX", Elastic.easeOut,  mc.scaleX, 1, tween_duration, true);
    new Tween(mc, "scaleY",  Elastic.easeOut, mc.scaleY, 1, tween_duration, true);
     tn_title.text = title_list[s_no];
    tn_desc.text =  description_list[s_no];
    tn_url.text = url_list[s_no];
