I am getting this error "UnityException: You are not allowed to call this function when declaring a variable. Move it to the line after without a variable declaration." But the only function im calling while declaring a variable is Instantiate. Here's my script -

var target;
//target = transform.Find("Character");

var damp : int = 3; 
var attackRange = 3; // safe distance from the player
var followRange = 50; //distance required for enemy to start following
var bulletPrefab : Transform; 
var savedTime = 0;
var explosionPrefab : Transform;

var hitPoints = 3;

function Update () 
{   
    target = GameObject.FindWithTag("Player");

    if((followRange > Vector3.Distance(target.transform.position, transform.position )) && (attackRange != Vector3.Distance(target.transform.position, transform.position ))) // if the enemy is closer than the follow range
    {
        follow(target);
    }

    var seconds : int = Time.time;
    var oddeven = (seconds % 2);

    if ((attackRange >= Vector3.Distance(target.transform.position, transform.position )) &&(oddeven))
        Shoot(seconds);
}

function follow(target)
{
        if( attackRange < Vector3.Distance(target.transform.position, transform.position)) //if enemy is farther than attack range
    {
        transform.LookAt(target.transform); //look at target
        transform.Translate (0,0,6*Time.deltaTime, Space.Self ); //move towards target
    }
}


function Shoot(seconds)
{
    if(seconds != savedTime)
    {
        var shoot = Instantiate(bulletPrefab, transform.Find("BulletSpawn").transform.position, Quaternion.identity);
        shoot.gameObject.tag = "enemyProjectile";
        shoot.rigidbody.AddForce(transform.forward * 1000);

        savedTime = seconds;
    }
}

function OnTriggerEnter(hit : Collider)
{
    if(hit.gameObject.tag == "fallout")
    {
        Die();
    }

    if(hit.gameObject.tag == "playerProjectile")
    {
        hitPoints -= 1;
        Destroy(hit.gameObject);

        if(hitPoints < 1)
        {
            Die();
        }
    }
}

function Die()
{
    Destroy(gameObject);
    var explode = Instantiate(explosionPrefab, gameObject.transform.position, Quaternion.identity);
}
