[MX] controlling external clip timelines...?

Hi all just wondering if anyone can fill me in on how to control the timeline of a movie clip which is contained within an externally loaded swf. I have a central window where images fade in and out of one another and I want the user to be able to pause the fade and play it as they please. This is the code I am using to load the external clip:

_root.createEmptyMovieClip(“profilesCentre”, 3);
loadMovie(“profilesCentreEX.swf”, “profilesCentre”);
profilesCentre._x = 17;
profilesCentre._y = 209.6;

I’m a little confused as to whether I should use “profilesCentre” as the object or “profilesCentreEX”…

thanks in advance! :smiley:
