Jumping to a frame *inside* a loading swiff

I have this code on the home page of a site:

_root.createEmptyMovieClip(“loadExternalSwiffs_mc”, 2);
loadExternalSwiffs_mc._x = 0;
loadExternalSwiffs_mc._y = 103;

The “introSplashPage.swf” it loads initially has buttons on it that swap in one or another swiff in its place, for instance, “mediaPage.swf”

This works OK, but in the case of “mediaPage.swf” I’d prefer that the button take the viewer directly to a labeled frame inside the swiff. I can’t figure out how to do that.

Online, I saw tantalizing code that used…
on (press) to get to the new swiff and then…
…to get to a specific, numbered frame. But I couldn’t get it to work, either going to my my frame number or, when modified, to my label.
