Load external text into scrolling text frame?

Hi, it’s my first post! I just did the Kirupa tutorials on using css styles in flash - perfect! I am having trouble applying it to my flash file though. Probably because I’m using a scrolling text layer to fit a thousand words or so.

This is based on actionscript.org script for scrolling text layers (I believe it was this one I used.
The button calls an .as file

#include “about.as”

which contains all the script for scrolling the chosen text file in your assigned text box. All I want to do is tell the chosen text file to use my actionscript

So do I have to add something in the .as file, or in my flash doc itself? What and where do I put it?

Many thanks
