How do i play this movieclip (it's a child)

1

i have an empty mc on the stage named adobeNu. in my library i have a mc named adobeNuMov. i exported this clip and linked it to a mc class(flash.display.MovieClip) named nuClips.

all i want to do is play the adobeNuMov clip when the button is clicked.

the following code isn’t working. nor does it work when the function is adobeNu.adobeNuMov.play(); or adobeNuMov.play();

???

 
var adobeNuMov:nuClips = new nuClips()
adobeNu.addChild(adobeNuMov);
 
button6.addEventListener(MouseEvent.CLICK, loadGraphic);
 
function loadGraphic (event:MouseEvent):void {
adobeNu.play();
}

is there a better way to dynamically load (and reference) movie clips from my library. my only goal in doing so is to reduce initial loading time of the the main swf, and to save loaded memory usage.
