Accessing array data

Hi all,

How do I access an array inside an .swf that is loaded using loadMovie?

this.createEmptyMovieClip(“controlpanel”, 999);
loadMovie(“lessons/regulatoryrequirements.swf”, controlpanel);

forward_btn.onRelease = function() {
attachMovie(screen_array[0], “currentscreen”, 0, {_x:500, _y:360});
};

screen_array is the array I’m trying to access in regulatoryrequirements.swf.

thanks!
