How to display highscore...

I have it to where the high score is saved but when I try to display it, i need to play the game first then it will show up later, I don’t want it to be 0 then what ever number it is.

here a small part of the script with the high score (C#)

public static int score;
	//Highscore
	public static int highScore;
	string highScoreKey = "HighScore";

void OnDisable(){
		
		if (score > highScore) {
			PlayerPrefs.SetInt (highScoreKey, score);
			PlayerPrefs.Save ();
		}
	}

And here is the script where I display the high score

//HighScore
		GUI.Box (new Rect (10, 10, 200, 80), "Highscore Table");
		GUI.Box (new Rect (10, 30, 200, 20), Player_Normal.highScoreToString ());

There should be dot before “ToString”, but it is not important.

Replace “Player_Normal.highScoreToString ()” to "PlayerPrefs.GetInt (“HighScore”).ToString ();

I ended up doing this and It works now.

using UnityEngine;
using System.Collections;

public class MainMenu : MonoBehaviour {
	//Normal
	public string normalLevel;
	public string Normal;
	string highScoreKey = "HighScore";


	// Use this for initialization
	void Start () {
		Normal = PlayerPrefs.GetInt (highScoreKey).ToString();
	}
	
	// Update is called once per frame
	void Update () {
	
	}

	void OnGUI(){
		if (GUI.Button (new Rect (Screen.width / 2 - 100 , Screen.height / 2 - 100, 200, 40), "[N]ormal")) {
			Application.LoadLevel (normalLevel);
		}
		if (GUI.Button (new Rect (Screen.width / 2 - 100 , Screen.height / 2 - 60, 200, 40), "~~tore")) {~~

~~ store();~~
~~ }~~
~~ if (GUI.Button (new Rect (Screen.width / 2 - 100 , Screen.height / 2 - 20, 200, 40), “[Q]uit”)) {~~
~~ Application.Quit ();~~
~~ }~~

~~ //HighScore~~
~~ GUI.Box (new Rect (10, 10, 200, 80), “Highscore Table”);~~
~~ GUI.Box (new Rect (10, 30, 200, 20), "Normal: " + Normal);~~

~~ }~~

~~ void store(){~~

~~ }~~
}
