Help with scroll bar on external swfs

hi all,

i have created transitions between external swifts with this tutorial http://www.kirupa.com/developer/mx2004/transitions.htm

I’ve created a scroll bar and it works when i test the external swift but when I test the main movie everything works except the scroll bar.

I made the scroll bar using movieclips, may this be the problem?

I would really appreciate any help, If you need more information just let me know.

thanks
