BCE 0005 unknown identifier error when accessing global variable.

I have a problem here, i am trying to make a life display with 3 images. when the character touches a trap it has a life deducted.
i have declared the LIVES to be global but when i try to access it using my fpswalker it come with error bce0005 unknown identifier

var health1: Texture2D;// 1 life left
var health2: Texture2D;//2 life left
var health3: Texture2D; //full  health


static var LIVES =3; // Global variable(static) - accessible by any script

function Update () {
	print("Lives: "+ LIVES + "Hits: "+HITS); 
	switch(LIVES){
		case 3:
			guiTexture.texture = health3;
		break;
		case 2:
			guiTexture.texture = health2;
		break;
		case 1:
			guiTexture.texture = health1;
		break;
		case 0:
			//gameover script
		break;
	}
	
}

Below is my fpswalker script.

var speed = 6.0;
var jumpSpeed = 8.0;
var gravity = 20.0;

private var moveDirection = Vector3.zero;
private var grounded : boolean = false;

function OnTriggerEnter(hit: Collider){ //hit is a controllercolliderhit type
	if(hit.gameObject.tag == "TrapPoison"){
		HealthCtrl1.LIVES -=1; 
// this is the part getting error when trying to run
	}
}
function FixedUpdate() {
	
	if (grounded) {
		// We are grounded, so recalculate movedirection directly from axes
		moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
		moveDirection = transform.TransformDirection(moveDirection);
		moveDirection *= speed;
		
		if (Input.GetButton ("Jump")) {
			moveDirection.y = jumpSpeed;
		}
	}
	// Apply gravity
	moveDirection.y -= gravity * Time.deltaTime;
	
	// Move the controller
	var controller : CharacterController = GetComponent(CharacterController);
	var flags = controller.Move(moveDirection * Time.deltaTime);
	grounded = (flags & CollisionFlags.CollidedBelow) != 0;
}

Àre you sure that your class is called HealthCtrl1? What’s the exact error? It normally prints the unknown identifier’s name.

Oh and btw. static != global. static means the variable belong to the class instead of a class instance.

edit

If you would read the error it says: “BCE0005: Unknown identifier: ‘HITS’.”
Why don’t you read the error completely or post at least the whole error. It says clearly that the unknown identifier is HITS!

i have pressed on the comment button. the naming convention is correct.

,my javascript is created and named as HealthCtrl1. is this the class name? by using static it means i can access with other script in the same project correct?

This is the error message i got:
Assets/Standard Assets/Scripts/FPSWalker 2.js(10,17): BCE0005: Unknown identifier: ‘HealthCtrl1’.
