Hopefully, my title explains the problem I’m having.

Basically, I’m making a webpage (my main swf) that loads in all kinds of other external swfs. I have a little bar that hovers above the external swf (after it’s loaded) which can be dragged around by the user. My question: how can I make the width of the drag bar always equal to the width of the external swf’s stage?
