Thumnails on XML Picture Viewer problem

Hi im having problems i have the xml photo gallery on my site but the hit_left and hit_right are in the right places but when i runj my movie you can hover towards hit_right at the far end of the pictures it will scroll but if you hit the left side it starts scrolling from half way to see an example look at the “gallerys pictures” on http://www.djmalc.com the movie is contained in a movie clip but the photos from the gallery on the home page work fine (not in a movie clip) Cheers for any help I’ll be re doing the gallerys with a bit of fancy stuff as im now learning more but still curious to whats gone wrong (The code is identical to the tutorial on kirupa.com)
