loading movie clip to stage with button click AS3

[good_snow]

I'm trying to figure out how to load a movie clip to the stage with a button click and have the movieclip close again using a close button. Does anyone have a step by step on how to do this or links to some tutorials.

Below is an example of what I'm trying to do.

Look up addChild and removeChild in the live docs....it allows you to add and remove items from the stage

openbtn0.addEventListener(MouseEvent.CLICK, openfunction, false, 0 , true);
closebtn0.addEventListener(MouseEvent.CLICK, closefunction, false, 0 , true);
function openFunction(e:MouseEvent):void{
addChild(movieClip0);
}

function closeFunction(e:MouseEvent):void{
movieClip0.parent.removeChild(movieClip0);
}
