What can I do about this error?

Currently I have an object that should die (Destroy currently) when health <= 0 and instead I get this error

here is the code that should rid me of the object:

// vars
var health : float = 100;
var armour : float = 0;
var shield : float = 0;

// supporting vars
var damage_hull : float = 0;
var damage_shield : float = 0;
var temp : float = 0;

// control vars
var replace : boolean = false;

// objects
var explosion : Transform;
var replacement : Transform;
var origional : Transform;

function Update () 
{
    if (health > 0.0 && shield <= 0.0)
    {
        if (armour > 0)
        {
            armour = armour - ( damage_hull / 2 );
            temp = damage_hull - armour;
            if (temp > 0)
            {
                damage_hull = temp;
            }
        }

        health = health - damage_hull;
    }

    if (health <= 0.0)
    {
        if (replace == false)
        {
            //Instantiate(explosion,transform.position, transform.rotation);
            Destroy (origional);
        }
        else
        {
            Instantiate(replacement,transform.position, transform.rotation);
            Destroy (origional);
        }
    }
}

function Hull_Damage_receiver (hull : float)
{
    damage_hull = hull;
}

function Shield_Damage_receiver (shield : float)
{
    damage_shield = shield;
}

Since "origional" is a Transform, I think you probably want:

Destroy( origional.gameObject );
