Error Accessing Other Script's Variables

 #pragma strict
 
 
 
 var aEnemy : Transform;
 
 var playerCharacter : GameObject;
 playerCharacter = GameObject.Find("First Person Controller");
 
 var script;
 script = playerCharacter.GetComponent(PlayerControl);
 
 var notesReceive : float = 0;
 notesReceive = script.notes;
 
 function OnTriggerEnter(other : Collider){
 
     if(other.gameObject.name == "First Person Controller"){
         Instantiate(aEnemy,Vector3(-1469.535,84.34768,408.0298),Quaternion(0,0,0,0));
         
         script.notes += 1;
         Debug.Log(script.notes);
         
         Destroy(gameObject);
         Destroy(GameObject.Find("KeyboxB"));
         
     }
 }

In my game, once the player reaches an objective, the global score is supposed to go up. In a script attached to a different object, there is a static var, notes. However, it doesn't seem to be changeable by other objects. I know asking this simple question may make me look like an idiot, but I must learn. The error is: Assets/Scripts/CollectB.js(14,23): BCE0019: 'notes' is not a member of 'Object'. However, this is repeated 3 more times throughout the script wherever the word "notes" is used...

I have tried working on this for hours on end, with different errors each time. I finally decided just to ask the community. Thanks to anyone who helps :)
