Loading Content Into Scroller Externally

Hi all,

I found a pretty clean and simple scroller, on this site which scrolls what ever is in a certain mc. I was wondering if anyone could take a look at the attached file and see if there is a way that I could have say six sperate piece’s of external .txt files and load each one externally? Even if someone could just show me how to do 1 with the attached would bea great!

Thanks!
