Flash MX 2004: Controlling External Swf (Nav)

I am creating a Flash program that consists of a “master” movie file that will call in individual chapters (*.swfs) as needed.

I want to create a single (page) navigation structure that will reside in the master - yet allow the user to go to the next/previous screens in the movie currently being used.

I have created the master movie and have placed an empty movie clip on one of the frames. From the main navigation, I have been successfully able to load the individual *.swfs into the empty movie clip when called from the menu using the following command:

_root.emptymovieclipname.loadMovie(“external.swf”);

I have been unable to figure out the action script that will allow me to control the navigation within the external swf from the main timeline. Any clues?

Also - is it possible to determine the number of frames within each clip as they are called so I can turn on/off the fwd/back buttons when appropriate?

TIA
