Calling a C# function from javascript error

Hi, Im trying to call a C# function from javascript but get the error

The name ‘FracturedObject’ does not denote a valid type (‘not found’).

with the below code, why?

#pragma strict

var ExplosionForce : float;
var explode : GameObject;
var explodeScript : FracturedObject; //c# script

function Start () {

	explode = GameObject.Find("Fractured Object");
	explodeScript = explode.GetComponent(FracturedObject);

	explodeScript.Explode(gameObject.transform.position, ExplosionForce);

One trick is to place the c# script in the “Standard Assets” directory.

You really just need it to be ahead of your javascript in the Compilation Order
