_x with loadMovieNum (Flash MX Pro 2004)

This should be easy, but of course nothing is as it seems.

loadMovieNum("/15x15002.swf",6);
_level6._x = 800;
_level6._y = 800;

It seems that I should be able to move the whole layer to position this .swf
Im going through hell getting the code and everything in this .swf to come in correctly any other way.
Is there a way to make this work? I cant seem to get a preloader or anything close to it. Ive moved the _x & _y to next frame and still nothing.
(I do spend a lot of time searching and experimenting before I post… sorry if it seems otherwise)

Thanks,
David
