Add a text media file that will scroll

[notsowiseone]

I love this script and am trying to figure out what to use for .txt files that can scrollin a text box?  I tried using a html textbox and set inital value to media_src and all I get is the path of the text file.  Tried several variations other that a javaSCRIPT DOC.WRITE type and all of them return the file path not the text?  Help would be muck appreciated
