Local connection for starting/stopping clips?

Hi Kirupa folks,

I just updated to Flash CS3 (yes, it is old, but affordable :D), and I just started to get into AS3 a bit. What I would like to know is, if what I am planning to do is possbile or not.

I have a navigation with a fairly simple roll over effect:

on (rollOver) {
    _root.nav1.gotoAndPlay(1);
}
on (rollOut) {
    _root.nav1.gotoAndPlay(13);
}

This results in a simple fade in and fade out effect sort of thing.

On the climax of this animation (frame 12) I would like to change the timeline of another swf file placed in the same HTML file.

I guess that a local connection will do this for me, but all the examples I have found so far deal with text boxes that send text from one swf to another by hitting a submit button.

But I want that during this navigation animation something like

_root.gotoAndStop(2);

is applied to the second swf, without user interaction.

Is that possible?

Many thanks in advance!
