Placing a Movie Clip Behind Another Movie Clip

Hello,
_
I have a a main movie containing a movie clip (say movie clip 1). Movie clip 2 is inside movie clip 1 (the _parent). Movie clip 2
contains a button with the following actionscript:
_
on (release) {
_parent.createEmptyMovieClip(“holder”, 1);
_parent.movie_clip_2.swapDepths(_parent.holder);
_parent.holder.loadMovie(“photo1.swf”);
_parent.holder._x = -140;
_parent.holder._y = -257; }
_
The problem I have is that the holder movie clip is in front of movie clip 2 whereas I would like it to be behind it.
_
What do you think? Thank you

have you done it both with and without the swapdepths step?
