From dynamically loaded hyperlink to Flash

Hi,
I have a dynamically loaded text file. In this file I want to make a hyperlink, by adding the HTML code to the file. I wonder if it is possible to make that hyperlink do something in a Flash Movie (like got to a certain frame making certain levels visible or invisible).
Maybe with the help of javascript.

I would be amazed, but also pleased if this turns out to be possible!

I can’t make a button in Flash, because the textfield is scrollable, and the button won’t move with the loaded text (although, writing this it occurs to me , that it maybe possible; make the position of the button respond to the position of the scrollbar, mmm)

Thank you,

Jerryj.
