Loading movies to a specific frame

Is it possible to load in a movie to a specific frame? I am currently loading a movie from a button with:
on (release) {
unloadMovieNum(1);
loadMovienum(“Is.swf”,0);
}

This works perfect, but I’d like to add usablility by directing the button to a specific frame within that new movie. I’ve tried:
_level0.gotoAndPlay(10);
after loadMovienum in the previous code but it doesn’t do anything different. The movie always starts up on frame 1.

In the end I’d like to have multiple buttons serving as navigation buttons specifying different frames of the new movie.

Am I close or is this not even possible? Thanks!!
