Scroller Text

Hello

Gurus

I have three movie clips on the stage. When I clicked the “but_one” movie clip a scroller come down with a text in it. Is it possible to load different text from three different text file ( so that it is easy to edit) in the scroller when clicked “but_two” and “but_three” . What I mean to say I want to load different text from text file when clicked different buttons. How can I do it with limited coding.

Thanks for reading.
