Scroller, duplicateMovieClip & xml problem!

First of all I may say I have a working action script wich loads from an external xml and duplicates movieclips for each news. That works ok!, but I have a problem with a scroller I want to use with that duplicated movieClips.

The scroller itself works fine with content I put into a clip (let’s call it X), but when I put the moviclip wich duplicates itself inside X, I can no longer scroll the content. But the duplication is correct!

To scroll content I need a larger content than the mask I use to scroll inside X, but the dupliated clips are larger enough. So… anybody has a clue of what’s going on?
