External txt

I am sure somewhere this has been talked about… but being a new guy here… I can not find it.

My problem:
I like to have a page ( in flash ) with buttons with headlines, when clicking on it on the right ( or wherever ) I have a text box and I like this text ( story ) to pop in that text box. My text files would all be save in a folder as .txt files.

Hope the question was clear if not I could do a screen grab
