Actionscript text animation

Hello all.

I was viewing this tutorial on kirupa about text animation,
and downloaded the source file. I started playing around with it because I want to do something similar with dynamic text but with lines of text rather than individual characters but I had no luck. As of now I’m just not that advanced in actionscript. Of course when I tried to email the author the email was indeliverable because it no longer existed. So I now turn to you. Anybody have any ideas?
