Hey guys, im starting do make a RPG game and in the Level system script(I called it "PlayerStatsController") i have an error: Parser Error : Unexpected symbol `public'. My script above:

 using UnityEngine;
 using System.Collections;
 
 public class PlayerStatsController : MonoBehaviour {
 
     public static PlayerStatsController intance;
 
     public int xpMultiply = 1;
     public float xpFirstLevel = 100;
     public float difficultFactor = 1.5f;
     
 
     // Use this for initialization
     void Start () {
         intance = this;
         DontDestroyOnLoad (gameObject);
         Application.LoadLevel ("GamePlay");
 
 
     }
     
     // Update is called once per frame
     void Update () {
     
     }
 
     public static void AddXp(float xpAdd){
                 float newXp = (GetCurrentXp () + xpAdd) * PlayerStatsController.intance.xpMultiply;
         if(newXp >= GetNextXp()){
             AddLevel();
             newXp = 0;
                 PlayerPrefs.SetFloat ("currentXp", newXp);
         }
 
     public static  float GetCurrentXp(){
                 return PlayerPrefs.GetFloat ("currentXp");
         }
 
     public static int GetCurrentLevel(){
                 return PlayerPrefs.GetInt ("currentLevel");
         }
 
     public static void AddLevel(){
                 int newLevel = GetCurrentLevel () + 1;
                 PlayerPrefs.SetInt ("currentLevel", newLevel);
         }
 
     public static float GetNextXp(){
         return PlayerStatsController.intance.xpFirstLevel * (GetCurrentLevel () + 1) * PlayerStatsController.intance.difficultFactor;
     }
 
 
     void OnGui(){
                 GUI.Label (new Rect (0, 0, 200, 50), "Current XP = " + GetCurrentXp ());
                 GUI.Label (new Rect (0, 15, 200, 50), "Current Level = " + GetCurrentLevel ());
                 GUI.Label (new Rect (0, 30, 200, 50), "Current Next Xp = " + GetNextXp ());
         }
 }
