XML Photo Gallery with Thumbs Help!

I have sucessfully managed to get the gallery to work in its own movie, but when I try to make it a movie clip and load/play it into another movie(which is my main skeleton for the site), the thumbnail part does not scroll or show all the images. The site is for a photographer, with three seperpate galleries. When a person visits the site, the see 3 menu options (wedding/travel/portrait) and they can click to see the chosen gallery. The gallery doesnt work once its loaded into the main movie. Any help would be great!
