Enabling and disabling buttons

i have a movie with this button which disables it upon loading of external .swf file:

on(release) {
loadMovieNum (“lg_01.swf”, 2);
i1.enabled = false;

the site in progress: http://www.pixeltheatre.com/c2m_flash/

How do i tell said .swf file to re-enable the “i1” instance from the original .swf file it loaded into? I guess where I’m getting lost is how to tell one .swf to affect another.

I think if i knew this little tidbit, I would most definitely be able to have more control over my sites.

I’m a self-taught novice actionscripter and obviously don’t know enough to do something as simple as this.

Any help would be greatly appreciated.

Thanks, Sean
