Loading multiple txt. files

O.K., I learned how to externaly load text in my movie. It loads into a slideshow.Now I want a second txt.file to load on the second slide. I tried several things but couldn’t figure it out. Here’s the code:

_root.block_mc.onEnterframe = function() {
_root.block_mc.textfileUrl = “pirate.txt”;
_root.block_mc.gotoAndPlay(2);

Anyone can help me?

regards
