GetComponent, Object Reference not set to an instance of an object

Hey all, love this site on so many levels. Time to ask a question of my own, though.

I have a script I am using to attach to doors (OpenableDoor), and passing it an "OpenDoor" script attached to my camera so it can read a raycast in order to determine if the player is actually looking at the door.

Now, this works perfectly fine. When the PlayTest first runs, it throws a NullReferenceException the first frame for all of the doors this is attached to, I am assuming because the raycast hasn't had a chance to properly hit something yet. All of the doors open perfectly fine, so on and so forth, and a NullReferenceException is not thrown until I end the PlayTest.

The issue I am having is with my "OpenLargeGarage" script. It is a near exact copy of my "OpenableDoor" script, except it uses a transform instead of a rotation (obviously, for a different kind of door). Unlike my other doors, however, it is constantly throwing out multiple NullReferenceExceptions on every frame, even though it is referencing the same camera the "OpenableDoor" script is. The error is thrown on line 8 of the "OpenLargeGarage" script.

EDIT: I also forgot to mention that it will not let me open the door that has the "OpenLargeGarage" script on it.

If anyone can help me, it would be appreciated. I have been researching for the past few days trying to fix this, but it is completely baffling how one script is working with the main camera, while the second script says the script on the main camera is Null. I really have no idea what is going on.

It wont let me attach my scripts, saying the file type is invalid. Not sure what's up with that.

As a quick re-cap: "OpenableDoor" is attached to a door. I feed it both a door object, and the main camera. "OpenLargeGarage" is attached to a different kind of door. I feed it both a door object, and the main camera. "OpenableDoor" does not through NullReferenceExceptions, while "OpenLargeGarage" does.

Here is the "OpenableDoor" script:

 // Smothly open a door
 var smooth = 2.0;
 var DoorOpenAngle = 115.0;
 private var open : boolean;
 private var enter : boolean;
 var door : GameObject;
 public var targetObj : Transform;
 public var targetScript : OpenDoor;
 
 private var defaultRot : Vector3;
 private var openRot : Vector3;
 
 function Start(){
 targetScript = targetObj.GetComponent(OpenDoor);
 defaultRot = transform.eulerAngles;
 openRot = new Vector3 (defaultRot.x, defaultRot.y + DoorOpenAngle, defaultRot.z);
 }
 
 //Main function
 function Update (){
 
 if(open){
 //Open door
 door.transform.eulerAngles = Vector3.Slerp(transform.eulerAngles, openRot, Time.deltaTime * smooth);
 }else{
 //Close door
 door.transform.eulerAngles = Vector3.Slerp(transform.eulerAngles, defaultRot, Time.deltaTime * smooth);
 }
 
 if(Input.GetKeyDown("e") && enter == true && targetScript.raycheck == true){
 open = !open;
 }
 }
 
 function OnGUI(){
 if(enter){
 //GUI.Label(new Rect(Screen.width/2 - 75, Screen.height - 100, 150, 30), "Press 'F' to open the door");
 }
 }
 
 //Activate the Main function when player is near the door
 function OnTriggerEnter (other : Collider){
 if (other.gameObject.tag == "Player") {
 enter = true;
 }
 }
 
 //Deactivate the Main function when player is go away from door
 function OnTriggerExit (other : Collider){
 if (other.gameObject.tag == "Player") {
 enter = false;
 }
 }

This is the "OpenDoor" script:

 #pragma strict
 
 private var guiShow : boolean = false;
 private var isOpen : boolean = false;
 
 //var door : GameObject;
 public var raycheck = false;
 
 
 
 var rayLength = 10;
 
 function Update()
 {
     var hit : RaycastHit;
     var fwd = transform.TransformDirection(Vector3.forward);
     raycheck = false;
     
     if(Physics.Raycast(transform.position, fwd, hit, rayLength))
     {
         if(hit.collider.gameObject.tag == "Door")
         {
             raycheck = true;
             guiShow = true;
             if(Input.GetKeyDown("e") && isOpen == false)
             {
                 //door.animation.CrossFade("DoorOpen");
                 isOpen = true;
                 guiShow = false;
             }
             
             else if(Input.GetKeyDown("e") && isOpen == true)
             {
                 //door.animation.CrossFade("DoorClose");
                 isOpen = false;
                 guiShow = false;
             }
             
         }
     }
     
     else
     {
         guiShow = false;
     }
 }
 
 function OnGUI()
 {
     if(guiShow == true && isOpen == false && raycheck == true)
     {
         GUI.Box(Rect(Screen.width / 2, Screen.height / 2, 100, 25), "Open Door");
     }
     if(guiShow == true && isOpen == true && raycheck == true)
     {
         GUI.Box(Rect(Screen.width / 2, Screen.height / 2, 100, 25), "Close Door");
     }
 }
 

Here is the "OpenLargeGarage" script:

 // Smothly open a door
 var smooth = 2.0;
 var DoorOpenHeight = 3;
 private var open : boolean;
 private var enter : boolean;
 var door : GameObject;
 public var targetObj : Transform;
 public var targetScript : OpenDoor ;
 
 private var defaultPos : Vector3;
 private var openPos : Vector3;
 
 function Start(){
 targetScript = targetObj.GetComponent(OpenDoor);
 defaultPos = transform.position;
 openPos = new Vector3 (defaultPos.x, defaultPos.y + DoorOpenHeight, defaultPos.z);
 }
 
 //Main function
 function Update (){
 
 if(open){
 //Open door
 door.transform.position = Vector3.Lerp(transform.position, openPos, Time.deltaTime * smooth);
 }else{
 //Close door
 door.transform.position = Vector3.Lerp(transform.Position, defaultPos, Time.deltaTime * smooth);
 }
 
 if(Input.GetKeyDown("e") && enter == true && targetScript.raycheck == true){
 open = !open;
 }
 }
 
 function OnGUI(){
 if(enter){
 //GUI.Label(new Rect(Screen.width/2 - 75, Screen.height - 100, 150, 30), "Press 'F' to open the door");
 }
 }
 
 //Activate the Main function when player is near the door
 function OnTriggerEnter (other : Collider){
 if (other.gameObject.tag == "Player") {
 enter = true;
 }
 }
 
 //Deactivate the Main function when player is go away from door
 function OnTriggerExit (other : Collider){
 if (other.gameObject.tag == "Player") {
 enter = false;
 }
 }

 var targetScript : OpenDoor = targetObj.GetComponent(OpenDoor);

 targetScript = targetObj.GetComponent(OpenDoor);
