Hey guys,

I am trying to reference to top level (stage) width and height of the main stage for the placement of something located inside a movieclip on the stage.

My code is:

```auto
    my_loader.x = (stage.stageWidth - my_loader.width)/2;
    my_loader.y = (stage.stageHeight - my_loader.height)/2;

```

But this seems to just relate to the width/height of the mc that my\_loader is nested in…

I have tried the following and had no luck:  
stage.stage.stageWidth  
root.stage.stageWidth  
parent.stage.stageWidth  
MovieClip(root).stage.stageWidth

What is the correct code? or am i doing something else wrong?
