Cannot use Static var/ Unknown Idientifier

Greetings,

I'm trying to use a static var, but unity tells me it's a Unknown Identifier. My other static var works perfectly, exception this one.

Here where's the bug

     if(other.tag == "Player"){
     doorSpawn = goToDoorNum;
     Application.LoadLevel("L"+gameLevel+"R"+goToRoomNum);
 }

gameLevel and doorSpawn are both static var declared here in another script:

 //At which door does the character spawn.
 static var doorSpawn : int;
 
 //Which game level are we in.
 static var gameLevel : int;

But only gameLevel return me an error. Any idea on how to force Unity to compile it correctly?

Edit:

Script A:

  //At which door does the character spawn.
 static var doorSpawn : int;
 
 //Which game level are we in.
 static var gameLevel : int;
 
 //In which room the character is.
 private var charInRoom : int;
 
 //In which room the boss is.
 private var bossInRoom : int;
 
 //How many rooms there is.
 var roomsQty : int;
 
 private var enemiesInRoom : int[];
 
 function Awake(){
     //Resize a native array.
     enemiesInRoom = new int[roomsQty+1];
     
     DontDestroyOnLoad (transform.gameObject);
     print(enemiesInRoom.Length);
 }
 
 function Update () {
 }
 
 function charRoomUpdate(room : int){
     charInRoom = room;
 }
 
 function spawnCharacter(){
     if(gameControl.isPlaying){
         var DoorSpawn : GameObject;
         GameObject.Find("Door"+doorSpawn;)
         SendMessage.DoorSpawn(spawnCharacterDoor);
     }
 }

Script B:

 //The number of the door.
 var doorNum : int;
 gameObject.name = "Door"+doorNum;
 ;
 
 //The room number to which the character will go.
 var goToRoomNum : int;
 //The door number the character should spawn at in the next room.
 var goToDoorNum : int;
 
 
 function OnTriggerEnter(other : Collider){
     if(other.tag == "Player"){
     
         doorSpawn = goToDoorNum;
         Application.LoadLevel("L"+levelManager.gameLevel+"R"+goToRoomNum);
     }
     
 }
 
 function spawnCharacterDoor(){
     SpawnPoint : GameObject;
     GameObject.Find(gameObject.name+"/Spawn");
 }
