JavaScript Timer/Highscore Problem

I tried to make a script which would let me press a button to see the current time that has passed since the level started but it just prints 0 when i press the button. I have pressed I to stop the recording and tried in many different ways. Im a bit new to java so please be patient with me. Thanks for any help i might get.

here is my codes:

 static var record : boolean;
 static var currentTime : float;
 static var bestTime : float;
  
 function Start () {
     // Reset current time
     currentTime = 0.0;
  
     // Start record
     StartRecord();
 }
  
 function Update () {
     // Keep adding to currentTime if record is true
     if (record)
         currentTime += 1*Time.deltaTime;
  
     // If Player press R then run Respawn function
     if (Input.GetKeyDown(KeyCode.R))
         Respawn();
         
     // If Player press I then stop recording time
     if (Input.GetKeyDown(KeyCode.I))
         StopRecord(true);
 }
  
 function Respawn () {
     if (!Application.isLoadingLevel)
         Application.LoadLevel(Application.loadedLevel);
 }
  
 static function StartRecord () {
     record = true;
 }
 
 static function StopRecord (checkBestTime : boolean) {
     record = false;
     if (checkBestTime && currentTime<bestTime) {
         bestTime = currentTime;
         PlayerPrefs.SetFloat("Score", bestTime);
     }
 }

And this:

 function OnGUI () {
     if (GUI.Button (Rect (0,0,200,100), "Click for highscore")) {
         print (PlayerPrefs.GetFloat("Score"));
     }
 }
