Movie clip help

i have a movie clip which contains a button. i would like to use the createEmptyMovieClip function from that button to create teh new movie clip on the main stage. this is what i have on the button inside my movie clip

on (release)
{
_root.createEmptyMovieClip("pic_load", 2);
loadMovie("pics.swf", "pic_load");
pic_load._x = 386;
pic_load._y = 40;
}

it creates the movie clip am sure but it doesn’t appear on my screen. i’ve tried changing the x and y to see if it would appear somewhere else but i get nothing. i’ve also tried _root.loadMovie(“pics.swf”, “pic_load”)
but that open a whole new window with my x and y values
