JavaScript: GUI Box help

I'm getting a lot better in programming now. But I can't figure out the GUI problem that I am having. If you look down to function OnGUI() I want to display those lines that are in comments inside a single GUI box. Can anyone help me? Thanks! :)

 //HealthBar
 var currenthealth : int=100;
 var maxhealth : int=100;
 
 var display_1 : GUIText;
 
 
 //MagicBar
 var currentmagic : int=100;
 var maxmagic : int=100;
 
 var display_2 : GUIText;
 
 
 
 function update() {
 
 if (currenthealth < 0) {
 
 currenthealth = 0;
 
 }
 
 }
 
 if (currentmagic < 0) {
 
 currentmagic = 0;
 
 }
 
 
 
 function OnGUI() {
 
 //"Magic :  " + currentmagic + "/" + maxmagic;
 //"Health : " + currenthealth + "/" + maxhealth;
 
 }
