Attempting to store an Inventory Array in PlayerPrefsX

Bear with me here, there's going to be a lot of code.

Thanks to a couple of really awesome people (and thank God!) I was finally able to wrap my head around Playerprefs last night. No wonder everyone kept pus$$anonymous$$ng me in that direction, fantastic system! =) It's nearly perfect for what I need, except when it came to saving an inventory string. No worries, Uncle Google to the rescue. I found t$$anonymous$$s thread w$$anonymous$$ch lead me here. So, still using my Playerprefs I plugged PlayerprefsX into my project, and t$$anonymous$$ngs seemed to be fine until I tried to gametest, at w$$anonymous$$ch point I was met with an exception here: "The Int32 array cannot have 0 entries when setting Inventory UnityEngine.Debug:LogError(Object) PlayerprefsX:SetValue(String, IList, ArrayType, Int32, PlayerprefsX_SetValue$callable0$262_117) (at Assets/PlayerprefsX.js:264) PlayerprefsX:SetIntArray(String, Int32[]) (at Assets/PlayerprefsX.js:239) Newsavesystem:OnSave() (at Assets/scripts/Newsavesystem.js:48) $:MoveNext() (at Assets/scripts/Newsavesystem.js:" And outofarray error here: "IndexOutOfRangeException: Array index is out of range. Inventory.Update () (at Assets/scripts/Inventory.js:10)

Now, I realize that the errors are occurring on three different scripts, (one of w$$anonymous$$ch is massive) and I'm a big boy and am going to keep trying to figure t$$anonymous$$s out w$$anonymous$$le praying for an answer. Yes, I see that the console is even kind enough to show me what lines are screwing up where, but I'm far too green to know what it all means yet. (am learning, not just knowledge mooc$$anonymous$$ng, promise!) Please note, too, that my inventory system worked fine before I attempted to save it, so any errors have come since I added PlayerprefsX. Here are the scripts, starting with the inventory. God bless the brave soul who undertakes t$$anonymous$$s.

 //inventory
 static var inventoryArray : int[] = [0,0,0,0,0,0,0,0,0,0,0,0,0,0,0];
 var inventoryText : GameObject;
 
 
 
 
 function Update () {
 
 inventoryText.guiText.text = "Health Potion " + "[" + inventoryArray[0] + "]" + "\n" + "Hard Tack " + "[" + inventoryArray[1] + "]" + "\n" + "Water " + "[" + inventoryArray[2] + "]" + "\n" + "Apple Brew " + "[" + inventoryArray[3] + "]" + "\n";
 
 if(Input.GetButton("Stuff"))
 
 if(inventoryArray[0] > 0) {
 
 healthPotion();
 }
 if(Input.GetButton("Sword Slash"))
 
 if(inventoryArray[1] > 0) {
 
 hardTack();
 }
 }
 //inventoryArray[0]++;
 //inventoryArray[1] ++;
 
 function healthPotion ()  {
 
 Playerhealth.curHealth += 15;
 inventoryArray[0] -=1;
 }
 
 function hardTack ()  {
 
 Playerhunger.curHunger -= 5;
 inventoryArray[1] -=1;
 }

 OnLoad();

 }
  
  
  
  
 function autoSaveEnable() {
  
  for(var x = 1; x>0; x++) {
  
 yield WaitForSeconds(5);
  
 Debug.Log("save me");
  
 OnSave();

         PlayerprefsX.SetIntArray("Inventory", Inventory.inventoryArray);
  
  
  
        
  
      
  
     }

     {
  
    
  
         Debug.Log("loaded");
  
  
  
        Playerhealth.curXp = PlayerPrefs.GetInt("CurXp");
        Playerhealth.maxXp = PlayerPrefs.GetInt("MaxXp");
        Playerhealth.maxHealth = PlayerPrefs.GetInt("MaxHealth");
        Playerhealth.curHealth = PlayerPrefs.GetInt("CurHealth");
        Playerhealth.level = PlayerPrefs.GetInt("Level");
        Playermoney.curMoney = PlayerPrefs.GetInt("Money");
        Inventory.inventoryArray = PlayerprefsX.GetIntArray("Inventory");
