Load movie in a specific frame

Noobie here…Simple but I don’t get it

I am loading an external movie and I want it to load an specific frame (start) of that movie right after loading.

I am using this

on (release) {
loadMovieNum(“details.swf”, 0);
}

I read about the _level so I added

on (release) {
loadMovieNum(“revo details.swf”, 0);
_level1.gotoAndPlay(“start”);
}

But the movie keeps on loading on the first frame, not on the “start” frame

Help here…

Regards!
