Need help with scrolling marquee

I’m stumped on how to make a working marquee, despite the last two days of research, and my best efforts (though I do admit I’m still barely over a novice when it comes to actionscript, but I’m stubborn, and getting better daily).

At any rate, this is my scenerio:

I have four buttons. Each button has a primary function of taking you to a different scene, and a secondary function where some text (different text for each button) is displayed in a dynamic text box during onRollOver, which then goes away onRollOut.

The displayed text are all String variables in the script.

The dynamic text box needs to stay a certain size.

The text is longer than the dynamic text box.

So, right now, every last part of this works, the script pops into the dynamic text box and goes away just like it should.

How can I make the text scroll (like a marquee) and repeat indefinitely until you onRollOut?

Any help would be HUGELY appreciated.

Thanks.
