Loading and Saving

Trying to implement a basic saving system into my ball rolling game. Basically the functionality I am trying to ac$$anonymous$$eve is it auto saves w$$anonymous$$le you're playing, and on the menu, there is a Load button. T$$anonymous$$s is my saving class, attached to a game object using UnityEngine; using System.Collections;

 public class saving : MonoBehaviour {
 
     public static int currentLevel;
 
     void Awake()
     {
         DontDestroyOnLoad (transform.gameObject);
         currentLevel = PlayerPrefs.GetInt("LastLevelLoaded");
     }
 
     // Use t$$anonymous$$s for initialization
     void Start () {
     
     }
     
     // Update is called once per frame
     void Update () {
         if(Application.loadedLevel != currentLevel)
         {
             currentLevel = Application.loadedLevel;
             PlayerPrefs.SetInt("LastLevelLoaded",currentLevel);
         }
     }
 }

And t$$anonymous$$s is a loader, attached to a game object as well using UnityEngine; using System.Collections;

 public class Load : MonoBehaviour {
 
     void Awake()
     {
         DontDestroyOnLoad (transform.gameObject);
     }
     
     public void Loaders()
     {
         Application.LoadLevel (saving.currentLevel);
         // Call the LevelManager and set the last level.
 
     }
     
 
         
 
 }

When I initially press load on the menu, it reloads my "loading" scene, and when I go to play the main level, and then I click menu, and attempt to load it, it does not$$anonymous$$ng. It loads the menu again I believe.
