NullReferenceException: Object reference not set to an instance of an object - MonoBehaviour

[Supershandy]

This is driving me mad as this script should work and makes sense to me, basically where the error is occurring is where I want a MonoBehaviour script to be disabled/false and the other one to be true, here is the first 26 lines of code.

#pragma strict

//Inspector variables

public var actionOnSpotted : MonoBehaviour;
public var soundOnSpotted : AudioClip;
public var actionOnLostSight : MonoBehaviour;

//Private variables

private var player : Transform;
private var enemy : Transform;
private var visualArea : boolean = true;

function Awake ()

{
	player = transform;
	enemy = GameObject.FindWithTag("Enemy").transform;
}

function OnEnable()

{
	actionOnLostSight.enabled = true;
	actionOnSpotted.enabled = false;
}

Now it is saying the error is on line 26 and saying that it’s not referencing anything, but on the Inspector there is a script attached so in theory, this code should be working fine…Or am I missing something?

Try putting the “actionOnSpotted” script on Standart Assets folder so it would compile before other scripts.If that solves your problem that means it was about the compiling order.
