What is wrong with this?

I am being really stupid and I cannot figure out why the width and height trace out zero?


var container:MovieClip = new MovieClip();
container.width = 100;
container.height = 100;
container.x = 100;


addChild( container );

trace( 	"contains: " + contains( container ) + 
		"
" + "width: " + container.width + 
		"
" + "height: " + container.height +
		"
" + "x: " + container.x
		);
