Reference error -_- Annoyed please help
Okay so I am following a tutorial and yet again in the tutorial the guy jumped past the part where he fixed an error and now i am stuck trying to solve it. I am stuck and can't seem to figure out the next step on how to fix this error. (scripting is not my favorite) Any help is appreciated thanks. Here the errors:
NullReferenceException: Object reference not set to an instance of an object GameSettings.SaveCharacterData () (at Assets/Game Data/Player Data/Scripts/Character Stats/GameSettings.cs:24) CharacterGenerator.DisplayCreateButton () (at Assets/Game Data/Player Data/Scripts/Character Stats/CharacterGenerator.cs:116) CharacterGenerator.OnGUI () (at Assets/Game Data/Player Data/Scripts/Character Stats/CharacterGenerator.cs:52)
Heres my Codes.

pc.name = "Character";
_player = pc.GetComponent<PlayerCharacter>();
_player.Awake();
pointsLeft = Talent_Points;
for(int cnt = 0; cnt < Enum.GetValues(typeof(AttributeName)).Length; cnt++)
{
_player.GetPrimaryAttributes(cnt).BaseValue = Minimum_Starting_Attribute_Value;

}
}
private void DisplayPointsLeft()

{
GameSettings gsScript = GameObject.Find ("GameSettings").GetComponent<GameSettings>();
gsScript.SaveCharacterData();
Application.LoadLevel("DireQuest Game");
}
}
}
GAMESETTINGS
using UnityEngine;
using System.Collections;
public class GameSettings : MonoBehaviour {
// Use this for initialization
void Awake()
{
DontDestroyOnLoad(this);
}
void Start () {
}
// Update is called once per frame
void Update () {
}
public void SaveCharacterData()
{
GameObject pc = GameObject.Find("pc");
PlayerCharacter pcClass = pc.GetComponent<PlayerCharacter>();
PlayerPrefs.SetString("PlayerName", pcClass.Name);
}
public void LoadCharacterData()
{
}
}
Sorry for the length. Thanks again!

GameObject.Find("pc"); is returning null
Which means, in other words, that you don"'t have an object in your scene called "pc".
