ExpToLevel not increasing

Hi guys,i have been using this script for leveling in the game but i tried to simplify it to make it shorter then after i did that,my leveling stopped working.

NewScript:

 using UnityEngine;
 using System.Collections;
 using System;
 
 public class RankManager : MonoBehaviour {
     public int CurLevel;
     public string ExpToLevel;
     public string Exp;
     public static RankManager Inst;
     public int MaxLevel;
     public WeaponManager Player;
 
     // Use this for initialization
     void Start () {
         Debug.Log ("Getting xp");
         Exp = PlayerPrefs.GetString("PlayerScore");
         Debug.Log ("Got xp");
         //NextLevel = CurLevel + 1;
         Inst = this;
     }
 
 
     // Update is called once per frame
     void Update () {
         if (NetworkManager.Instance.MyPlayer.PlayerName != "") 
         {
             Player = NetworkManager.Instance.MyPlayer.Manager.FirstpersonCont;
 
             foreach(Gun g in Player.Weapons)
             {
                 if(CurLevel > g.UnlockLevel)
                 {
                     g.Unlocked = true;
                 }
                 else
                 {
                     g.Unlocked = false;
                 }
                 foreach(Sight s in g.Sights)
                 {
                     if(s.UnlockKills >= g.Kills)
                     {
                         s.Unlocked = true;
                     }
                     else
                     {
                         s.Unlocked = false;
                     }
                 }
             }
         }
     }
 
     void MultiplyExperience(){
         if (CurLevel >= MaxLevel)
         {
             CurLevel = MaxLevel;
         }
 
         int Compare = string.Compare(Exp, ExpToLevel);
         Debug.Log ("Compared");
             if (Compare == 0);
             else 
             if (Compare > 0) // More than ExpToLevel
             {
             CurLevel++;
             int exptolevel =  Convert.ToInt32(ExpToLevel);
             exptolevel *= 2;
             ExpToLevel = exptolevel.ToString();
             }
 
 
                 if(Network.peerType != NetworkPeerType.Disconnected)
                 {
                     NetworkManager.Instance.MyPlayer.Manager.networkView.RPC("UpdateRank",RPCMode.All,CurLevel);
                     PlayerPrefs.GetString("PlayerScore" + NetworkManager.Instance.PlayerName, Exp);
                     Debug.Log("RankManager Getting Int");
                 }
 
 }
 }

Old Script:

    //public int ExpToLevel;
     //public int Exp;
     public int CurLevel;
     public int NextLevel;
     public string ExpToLevel;
     public string Exp;
     public static RankManager Inst;
     public int MaxLevel;
     public WeaponManager Player;
     int i;
 
 
 
     // Use this for initialization
     void Start () {
 
 
         Debug.Log ("Getting xp");
         Exp = PlayerPrefs.GetString("PlayerScore");
         Debug.Log ("Got xp");
         //NextLevel = CurLevel + 1;
         Inst = this;
         if (int.TryParse(ExpToLevel, out i));
 
     }
 
 
     // Update is called once per frame
     void Update () {
         int xp;
         if (int.TryParse(Exp, out xp))
         //Exp = PlayerPrefs.GetInt ("PlayerScore");
         //Debug.Log ("Update xp");
 
         if (NetworkManager.Instance.MyPlayer.PlayerName != "") 
         {
             Player = NetworkManager.Instance.MyPlayer.Manager.FirstpersonCont;
 
             foreach(Gun g in Player.Weapons)
             {
                 if(CurLevel > g.UnlockLevel)
                 {
                     g.Unlocked = true;
                 }
                 else
                 {
                     g.Unlocked = false;
                 }
                 foreach(Sight s in g.Sights)
                 {
                     if(s.UnlockKills >= g.Kills)
                     {
                         s.Unlocked = true;
                     }
                     else
                     {
                         s.Unlocked = false;
                     }
                 }
             }
     }
         if (CurLevel >= MaxLevel)
         {
             CurLevel = MaxLevel;
         }
         //int ExpToLevel : String;
         //ExpToLevel = ExpToLevel.ToString();
         int result = string.Compare(Exp, ExpToLevel);
         if (result == 0);
             else if (result > 0) // More than enough
             {
                 CurLevel++;
                 NextLevel = CurLevel + 1;
             int exptolevel =  Convert.ToInt32(ExpToLevel);
             exptolevel *= 2;
             ExpToLevel = exptolevel.ToString();
 
             //ExpToLevel *= 2;
 
                 if(Network.peerType != NetworkPeerType.Disconnected)
                 {
                     NetworkManager.Instance.MyPlayer.Manager.networkView.RPC("UpdateRank",RPCMode.All,CurLevel);
                     PlayerPrefs.GetString("PlayerScore" + NetworkManager.Instance.PlayerName, Exp);
                     Debug.Log("RankManager Getting Int");
                 }
 
             }
 }
 }
 

ExpToLevel is not doubling when my exp is higher than it.
