Keep track of if something is within the trigger with a boolean. Then if that boolean is true, display the GUI :

 var withinTrigger : boolean = false;
 
 function OnTriggerEnter (other : Collider) 
 {
     withinTrigger = true;
 }
 
 function OnTriggerExit (other : Collider) 
 {
     withinTrigger = false;
 }
 
 function OnGUI()
 {
     if ( withinTrigger )
     {
         GUI.Box( Rect( (Screen.width * 0.5) - 100, 10, 200, 25 ), "Within the Trigger !" );
     }
 
 }

Ahh yeah I misread, I though he was using the guiText component ... its a much better idea to do it this way, although not sure why you used GUI.BOX over GUI.Label

Force of habit, I only use Unity's GUI for debugging / displaying stats while testing, and always use Box for that! I think it's for the contrast and the centering of the text. I have written and use my own GUI for my projects.

the code formatting has not included the first line, so if you just copied then you are missing the first line. I have just fixed the code block (the first line was always there, perhaps read the code?).

Are you familiar with trigger? http://www.unity3dstudent.com/2010/07/beginner-b13-trigger-collision-detection/
