help loading external movie in sprite

i'm trying to load an external swf into my main movie but i've just can't get it to work. i've followed some tutorials on the web but i am completely stuck. when i press the "foto's" button i want to load the movie gallery.swf nicely inside the rectangle but no matter what i try; sometimes the alignment is all scr*wed up or i don't see anything at all. any help is welcome tx.
