How to add and keep score in every level?

Hello all,
I’m a PhD student and I’m doing a simple game of collecting coins for my research. The question might be silly but I’m not a programmer. I’m trying to keep and add score in every level, but when the new scene is loaded the score starts again from the zero.
My code so far is:

       static var score=0; var guiScore :
       GUIText;
       
       function start () { 
       guiScore.text = "Coins: "+score;
       }
       
       function OnTriggerEnter (other :Collider ) 
      { 
      Debug.Log ("OnTriggerEnter () was called"); 
      if (other.tag == "Coin") { 
      Debug.Log ("Other object is coin");  	
      score ++;  	
      Debug.Log
      ("Score is now " + score);
      Destroy (other.gameObject);  	
      guiScore.text = "Coins : " +score; 
      Timer.onpause = true;  	
      Application.LoadLevel("Menu2");

}
}

I would really appreciate any help.
Thanks in advance.
