Loading external movies/games

hi everyone!

i want to make a flash site but i’ve run into a few issues,
i’ve made an empty movie clip called ‘empty’

and a button under it with the code
on (release) {
_root.empty.loadMovie(“example.swf”);
}

this works fine for movies, but not interactive movies and games, for some reasons i get error after error.
can anyone help me with this?

thanks.
