gameoverscript.js(1,1): BCE0044: expecting EOF, found 'gameOver'.

Your error is due to the line "`gameOver : boolean = false;`": add the word "var" at the beginning, like that:

 var gameOver : boolean = false;

However, there's another error, two lines ahead:

 if (CurrentTime = 0) 
 

is a test, not an assignment, so it would be:

 if (CurrentTime == 0)

If your script wouldn't work yet, my advice is to format the code properly in the question, so it will be more readable (just click on the 010101 button).

You've got two errors in Update() that I can see ...
if(CurrentTime = 0)...
your CurrentTime variable is 'currentTime' not CurrentTime (case-sensitive) and only one equals sign
...->
if(currentTime == 0) is what would be used for equal-to...

I'd go with this though->
if(currentTime
try fixing those and see if anything changes.

I having made changes to the code.

However the problem im having now is the "game over" message is appearing before the timer gets to 0.

------------timerscript--------------------

 // the textfield to update the time to

private var textfield:GUIText;

// time variables public var allowedTime:int = 5; var currentTime = allowedTime;

function Awake() { // retrieve the GUIText Component and set the text textfield = GetComponent(GUIText);

 UpdateTimerText();
 
 // start the timer ticking
 TimerTick();

}

function UpdateTimerText() { // update the textfield textfield.text = currentTime.ToString(); }

function TimerTick() { // while there are seconds left while(currentTime > 0) { // wait for 1 second yield WaitForSeconds(1);

     // reduce the time
     currentTime--;
 
     UpdateTimerText();
 }

 // game over
 //yield WaitForSeconds (10);
  //Application.LoadLevel ("Menu");

}

----------------game over script-----------------

 var gameOver : boolean = false;

var time : CountdownTimer;

function Update() { if (time.currentTime == 0) gameOver = true;

}

function OnGUI() { if (gameOver) GUI.Label(Rect(0,0, 100, 20), "Game Over");

}

Thanks for all the previous feedback!
