How to use same code at multiple scenes ?

For example I'm gonna make a choice at "Choice.js"

 public static var playerInt : int; 
     
     var playTypeString : String;
     
     function Start()
     {
     playerInt = 0;
     }
     
     function Update () {
     
     
     
     if(playerInt == 0) {
     playTypeString = "sphere";
     } else if(playerInt == 1) {
     playTypeString = "stick";
     } else if(playerInt == 2) {
     playTypeString = "plus";
     }
      
     var text = gameObject.GetComponent(TextMesh);
     text.text = playTypeString.ToString();
     }

At there I've set public static variable. I want to get it's value at Game Scene and i use this;

 function Start () {
 
 
 if(Choice.playerInt == "0" ){
 
 Debug.Log("player1");
 
 }
 
 if(Choice.playerInt == "1" ){
 
 Debug.Log("player2");
 
 }
 
 }

But didn't work.
