Problem loading SWF into project

1

Hi

I have create a 360 mouse control panorama view in swf format. I decided to load my swf into a container called “loader” to hold the movie’s size and location so that it wont appear on my buttons but it failed. I hav try the same way to load other swf but it works.What could be the problems?

This is my code

play_btn.onRelease=function(){
loadMovie (“LAMBO_INTERIOR3_out.swf”,"_root.loader" );
}

Thanks.
