Whenever you have text to display, don't forget to have a wait trigger.
Example:
Display the following text for 10000 milliseconds: I want to kill bunnies...
Pause for 10000 milliseconds
For every message you have, make sure it is displayed for X amount of time and have a Wait trigger for the same amount of time, or a little longer.
1000 milliseconds = 1 second
10000 milliseconds = 10 seconds
When you don't have a Wait trigger, the game likes to go through the triggers real fast then start the game play. Just add Wait triggers and it should work fine dude!
Also, Make sure that it is displayed for the player you want to read it. If its for player 1, make sure that you have the box for player 1 checked. Other then these two things, I'm not sure what else it could be.
