Why NullReferenceException??

Unity tells me that i have a problem in my script but i don't get what i need to change on it to make it work, this is the problem:

NullReferenceException: Object reference not set to an instance of an object
PickUpCamera.Start () (at Assets/PickUpCamera.js:14)

This is the Script:

Code (csharp):

1.  
2. var DigitalCameraHide : DigitalCameraScript;
3. //
4. var DigitalCameraObject: GameObject;
5. var PickupSound: AudioClip;
6.  
7. private var inTrigger = false;
8. //
9. private var hasDigitalCameraScript = false;
10. function Start ()  
11. {
12.  
13. DigitalCameraHide = GameObject.Find("Player").GetComponent(DigitalCameraScript);  
14. DigitalCameraHide.enabled = false;      
15.  
16.  
17.  
18. }
19.  

 

Are you sure you have a game object named "Player" that has the DigitalCameraScript on it?

Because it's not finding it.
