Controlling movies clips that are in a .swf on another level?

Ok, I thought I was getting good at scripting but I guess not lol!!

The situation:

On the bio page of a site I’m doing (the bio .swf is loaded into level 50), I have a “home” button there and I want the home button to direct the user back to the index .swf on level 0 and have the playhead start playing at **frame 130 of a movie clip in that index swf. **The movie clip on the index .swf is called “mc_header”.

Here is the script I have attached to the home button on the “bio .swf”:

on(release) {
/ this will unload the bio swf.
** unloadMovieNum(50);**
/this is supposed to make it play at frame 130 of the mc_header clip on the index swf/
** _level0.mc_header.gotoAndPlay(130);**
}

It (the screen) just goes black when I release the home button. What am I doing wrong?

Thanks,
