My XML gallery ..... again

This although good fun is very frustrating, if anyone can help me with this problem i would be very gratefull. Is there anyway i can have this fla file and place it in a movie clip so i can have several galleries all loading into the same file,

Basically i would like buttons on the right hand side loading each gallery into an empty movie clip on the left hand side, but as soon as i put all the gallery components into a movie clip they disapear!

Someone please help! Thanks
