Array value not changing?

it;s not changing for some reason, even though i tell it to add or subtract one when i press the buttons. can you tell me what i did wrong? (the message is displaying) but not changing.

script:

@script ExecuteInEditMode
static var pages : Array;
var levelToLoad : String = "Level1";
var first : String;
var second : String;
var third : String;
var fourth : String;
var fifth : String;
var sixth : String;
var seventh : String;
var rectangle : Rect;
var Rectangle : Rect;
var next : Rect;
var back : Rect;
var mssgRect : Rect;
var windowRect : Rect = Rect((Screen.width / 2) - (X / 2), (Screen.height / 2) - (Y / 2), WIDTH, HEIGHT);
var X : int;
var Y : int;
var X2 : int;
var Y2 : int;
var WIDTH : int;
var HEIGHT : int;
static var currentPage : int;
private var showGUI = false;

function Awake()
{
 currentPage = 0;
 showGUI = false;
}
function Start()
{
 pages = Array(first, second, third, fourth, fifth, sixth, seventh);
 currentPage = 0;
 print(pages[currentPage]);
}
function GoUpPage()
{
 if(currentPage < pages.length)
 {
  currentPage ++;
  print(pages[currentPage]);
 }
 if(currentPage > pages.length)
 {
  showGUI = true;
 }
}
function GoDownPage()
{
 if(currentPage > 0)
 {
  currentPage --;
  print(pages[currentPage]);
 }
}
function OnGUI()
{
 if(!showGUI)
 {
  windowRect = GUI.Window(0, windowRect, DoMyWindow, "Tutorial Info:");
 }
 if(showGUI)
 {
  windowRect = GUI.Window(1, windowRect, ShowGUI, "First Level?");
 }
}
function ShowGUI()
{
 GUI.skin.button.wordWrap = true;
 if(GUI.Button(back, "<--Back"))
 {
  GoDownPage();
  showGUI = false;
 }
 GUI.skin.button.wordWrap = true;
 if(GUI.Button(next, "Level 1-->"))
 {
  Application.LoadLevel(levelToLoad);
 }

 GUI.DragWindow();
}
function DoMyWindow()
{
 if(!showGUI)
 {
  GUI.skin.label.wordWrap = true;
  GUI.Label(Rect(X2,Y2,10000000, 50), "" + System.DateTime.Now);
  GUI.skin.button.wordWrap = true;
  if(GUI.Button(rectangle, "Next"))
  {
   GoUpPage();
  }
  GUI.skin.label.wordWrap = true;
  GUI.Label(mssgRect, pages[currentPage].ToString());
  GUI.skin.button.wordWrap = true;
  if(GUI.Button(Rectangle, "Back"))
  {
   GoDownPage();
  }
 }
 GUI.DragWindow();
}

thanks in advance!

(all the rects where to get the GUI positioning correct.)

If you're trying to get it rendering the GUI properly in editor mode, it probably won't work - unity doesn't update OnGUI much when it's not playing (Generally only does something when something happens to force a refresh)

If that's not the case and you're trying to get it to work at runtime, I'm not sure - your code works for me
