problem sending information from js script to c# script

I am try to send the score and name from my Js script to my c# script.

This is my js script its called Quest1;

 var VoiceClip : AudioClip;
 static var Counter : int;
 var soundplayed = false;
 
 var script : Highscore;
 script = GetComponent("Highscore");
 
 
 function update ()
 {
     if(Counter >= 1)
     {
     script.name = "David";
     script.score = Counter;
     script.StartCoroutine("GetScore");
     
     print("There was an error posting the high score: ");
     }
 
 }
 
 
 function Start()
 {
 if (!soundplayed) {
     audio.PlayOneShot(VoiceClip);
     soundplayed = true;
   }
         
 }
 function OnGUI()
 {
     GUI.Label (Rect (10, 10, 1000, 20), "Metors Destroyed: " + Counter);
 }
 
 function Update () 
 {
 if(Counter == 6)
 {
 
 GetComponent(Quest2).enabled = true;
 GetComponent(Quest1).enabled = false;
 
 }
 }

This is the C# script I want to send the data to: its called Highscore
