Having trouble using PlayerPrefs to save high score

Unity Engine
1

Hello I’m trying to save the player’s high score and display it another scene, using PlayerPrefs. Doing some searching I came across a local high score script but I’m not sure on how to incorporate it into my project correctly.

If it helps here is my scoring script, called ‘Score - Easy’:

private var powerUpAble = true;
var score = 0;
var DeductSlowDownScore = 65;
var scoreText = "Score: ";
var mySkin : GUISkin;

function OnTriggerEnter( other : Collider ) {
    Debug.Log("OnTriggerEnter() was called");
    if (other.tag == "Coin") {
        Debug.Log("Other object is a coin");
        score += 115;
        Destroy(other.gameObject);
	} 
        else if (other.tag == "Rock") {
        Debug.Log("Other object is a rock");
        score = Mathf.Max(0, score - 75);
    }
     	else if (other.tag == "Tree") {
        Debug.Log("Other object is a tree");
        score = Mathf.Max(0, score - 50);
    }

    scoreText = "Score: " + score;
    Debug.Log("Score is now " + score);

}

function OnGUI () {
	GUI.skin = mySkin;
    GUI.Box (Rect (140, 10, 500, 200), scoreText.ToString());
    if (powerUpAble)
    if (GUI.Button (Rect (5, 65, 110, 60), "Slow Down"))
        StartCoroutine( SlowDown( 1.5 ) );// deactivate for 1.5 secs
 
 	}


function SlowDown(deactivateInSeconds : float)
{
    var script4 = GetComponent("Raft Forward - Easy"); 
    script4.enabled = false;
    var script5 = GetComponent("RaftForwardEasier - Easy"); 
    script5.enabled = true;
    var script6 = GetComponent("Pause Button - Easy"); 
    script6.enabled = false;
    powerUpAble = false;

    yield WaitForSeconds(deactivateInSeconds);

    script5.enabled = false;
    script4.enabled = true;
    script6.enabled = true;
	score = Mathf.Max(0, score - DeductSlowDownScore);
	scoreText = "Score: " + score;
    Debug.Log("Score is now " + score);
    powerUpAble = true;

};

Attached to the same object that my scoring script is attached to is the local high score script I tried to use. I named the script ‘SaveScore’:

GetComponent("Score - Easy");
function AddScore(score : int){
   var newScore : int;
   var oldScore : int;
   newScore = score;
   for(i=0;i<10;i++){
      if(PlayerPrefs.HasKey(i+"HScore")){
         if(PlayerPrefs.GetInt(i+"HScore")<newScore){ 
            // new score is higher than the stored score
            oldScore = PlayerPrefs.GetInt(i+"HScore");
            PlayerPrefs.SetInt(i+"HScore",newScore);
            newScore = oldScore;
         }
      }else{
         PlayerPrefs.SetInt(i+"HScore",newScore);
         newScore = 0;
      }
   }
}

It was also said to initialise the high score call ‘AddScore’ at the start of the game, but I’m not sure how to do so.
And to display the score I tried to use this script, in another scene, called ‘ShowScore’:

var 1stScore : int;

function UpdateHScore(){
   1stScore = PlayerPrefs.GetInt(0HScore);
}

The problem is is that I can’t get it to work properly. The console is saying that the ‘1’ in ‘var 1stScore: int;’ is an unexpected token and I don’t know what to do.

Thank you greatly for any answers or feedback

You can’t start variables with a number, only a letter.
