External SWF Help

[spellbinder_4]

Hey all,
so I'm trying to load an external SWF file in to my AS2.0 flash page
iv managed to find the code that will display it ware i want it but its not playing like it should.. its an image gallery and one of the thumbnails flashes threw all my images, and i also don't get the enlargement of the images when i click it...
but this works in the original SWF .. any ideas?
hears what iv got to display it

if(this.stage_mc == Number(this.stage_mc)){
loadMovieNum("PhotoGallery.swf",this.stage_mc);
} else {
this.stage_mc.loadMovie("PhotoGallery.swf");
}
