Loading external photo gallery error

I have edited the photogallery tutorial with my own graphics and would now like to use it in my own flash movie. However when i link to it externally all it loads up on preview is the first image of the gallery with no buttons and no masks etc. Just the first JPEG.

I tried the bring the frames of the FLA into my own movie rather than linking to them externally, but the movie gave the the error NAN repeatedly.

All the files are in the correct locations as it works fine when i preview the swf of the gallery. Also the gallery works if im to preview just the scene that its in, rather that the whole movie.

Any clues anyone?
