C# Player Prefs & Toggle| Will not save settings

{UPDATED!} Hey guys, a little help here with a simple toggle:

The following script is suppose to change a material when toggle isON. The script works, in regards to changing the material, but it will not save the settings when I begin a new game. Does anyone know what I should do differently? The script is annotated, and the problem areas are specified for quick revision.

 using UnityEngine;
 using System.Collections;
 //Had to copy and paste this into my project folder from the unity packadge, 
 //not accessing for some reason...
 using UnityEngine.UI;
 
 
 public class swapMaterial : MonoBehaviour {
 
     //plug in material here
     public Material anyMat;
     //plug in default material here
     public Material defaultMat;
     //object that is effected by this script.
     public GameObject anyObject;
     //bool that decides if specified object changes material to gold
     public bool isGold;
     //this bool is simply here for comparative use.
     private bool sotrue = true;
     //A toggle that the user can switch on and off to select the gold material or not.
     public Toggle GoldenToggle;
 //The int that is being stored...
     private int midas;
 
 
     //public Component currentmaterial;
 
     void Awake(){
 
         //*****Help:Suppose to get the settings the player has chosen. Is it gold or not?
         midas = PlayerPrefs.GetInt("midas");
 
 //compares the stored int deciding whether material is changed or not...
         if (midas == 1) {
             isGold = true;
         } else {
             isGold = false;
         }
         
     }
     
 
     void Update(){
 
 
         //If bool isGold is true, change material to the material plugged into anyMat.
         if (isGold == sotrue) {
             anyObject.GetComponent<MeshRenderer> ().sharedMaterial = anyMat;
             midas = 1;
 
         } 
         else {
             //Else the material of this object is the selected default.
             anyObject.GetComponent<MeshRenderer> ().sharedMaterial = defaultMat;
             midas = 0;
 
 
 
         }
         //If the user has switched the toggle on, then the effected object's material becomes "anyMat"
         //in this case, Gold.
         if(GoldenToggle.isOn == true){
             isGold = true;
 
             //*****HELP: Suppose to save the toggle as on! not working...sets the int based on isGold in this case 1
             PlayerPrefs.SetInt("midas", midas);
 
 
 
         } //If the toggle is off, then the effected object's material becomes default.
         else {
             isGold = false;
             //*****HELP: Suppose to save the toggle as off! not working...sets the int based on isGold in this case 0
             PlayerPrefs.SetInt("midas", midas);
             
         }
 
         //Saves the player's selected settings. In this case, gold or no gold?
         //HELP:*****Does not apear to save the settings...problem in above script?
         PlayerPrefs.Save ();
 
     
 
     
 }
 
 }

This toggle is a setting to be applied to a new game, so the object in question is gold on new game, or not. I hope someone has a fresh perspective! Thank you all. Happy Deving!

For anyone needing help This script: Successfully changes a material. (scripted to be plunged-into the inspector) Successfully connects to a toggle.

Intended as a setting to be applied on New Game.
