Problem with Photo Gallery using XML and Flash with thumbnails

Hi. I am new here. Just want to say that you got a great tutorials on the thumbnail gallery.

I have tried to incorporate it into my flash site. But I have a problem running the scroller at the bottom when I put the movie in my main scene. It doesn’t scroll. The big pic will change perfectly when I clicked on the three thumbnails.

The scroller works when I run the movie on its own.

Can someone help?
