Reference error -_- Annoyed please help

[chrismcrae5712]

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.

GAMESETTINGS

	}
}

Sorry for the length. Thanks again!

GameObject.Find(“pc”); is returning null
