Error javascript

Unity Engine
1

my problem is that this error me: NullReferenceException: Object reference not set to an instance of an object
Boo.Lang.Runtime.RuntimeServices.InvokeBinaryOperator (System.String operatorName, System.Object lhs, System.Object rhs)
RespawnFirstPerson.Update () (at Assets/Nacho/Scripts/RespawnFirstPerson.js:2)

I think I want a static variable and pass it to another script

RespawnEscalera.js

static var miposicionZ;
miposicionZ = transform.position.z;
static var miposicionZ2;
miposicionZ2 = miposicionZ + 3;
static var miposicionZ3;
miposicionZ3 = miposicionZ -3;


static var miposicionX;
miposicionX = transform.position.x;
static var miposicionX2;
miposicionX2 = miposicionX + 16;

static var miposicionY;
miposicionY = transform.position.y;

RespawnFirstPerson.js

function Update () {
if (transform.position.x > RespawnEscalera.miposicionX  transform.position.x < RespawnEscalera.miposicionX2 
     transform.position.y < RespawnEscalera.miposicionY  transform.position.z > RespawnEscalera.miposicionZ2 
     transform.position.z < RespawnEscalera.miposicionZ3 ) 
{

    transform.position.x = 32;
	transform.position.y = 3.5;
	transform.position.z = -48;

}
}

With this script I want is that when I move the ladder, do not have to change the coordinates for the respawn

Thanks, I hope you know I answer :smile:

miposicionZ = transform.position.z; - should be in a start or awake function.

all variables in a start function?

Just the assigned references. (Tip) Its not a good idea to use static. GetComponent will help reduce any possible static problems.

static var miposicionZ : float;

function Start () {
    miposicionZ = transform.position.z;
}
