I am trying to get the thumbnail scroller to work inside a separate movie clip from the main time line. Ive got the thumbs to load fine but my main problem is that i cant click or interact with them. I’m using the xml photo gallery tutorial as a guide. I also attached the .fla. Any help would be greatly appreciated, my hair would also thank you.
