gotoAndPlay external .swf

I was wondering if there is a way to play a selected frame when you launch an external .swf. When the .swf is launched it plays for 20 frames, which is a tween of it growing up. I have a stop(); at frame 20, then frame 21-40 I reversed the frames so that is shrinks. I have labeled frame 21 as “e1”. On my main stage I have a button that when pushed I want to gotoAndPlay(“e1”) so that it looks like the external .swf shrinks. I hope I explained this well enough. Is this possible?

This code does not work, but it might explain what I am trying to do…

on (release){

As you can tell, my AS is very very poor.
