Can someone help

I add a external swf, how can have acess controlling the x and y of the swf, or controlling a mc inside the swf.

I try nameofswf.container.x and nameofswf.container.mc.x but dont work.

I Searched high and low and even liveDOCS hasnt got an answer.

Can someone give a answer or appoint me the correct path to find one?
