Error with Rigidbodies

Unity Engine
1 
//Textures for direction change
var leftTexture : Texture;
var rightTexture : Texture;

function Update () {

//Change texture

if(Input.GetButtonDown("A")){
	renderer.material.mainTexture = leftTexture;
}

if(Input.GetButtonDown("D")){
	renderer.material.mainTexture = rightTexture;
}

}

//Controls
var moveSpeed = 10;

function FixedUpdate () {
if(Input.GetAxis("W")){
	Rigidbody.AddForce(Vector3.forward * - moveSpeed);
}
}

That’s my code for trying to move my player with a Rigidbody. I get this error:

Assets/Standard Assets/Scripts/My Scripts/Character.js(24,19): BCE0020: An instance of type ‘UnityEngine.Rigidbody’ is required to access non static member ‘AddForce’.

The Player does in fact have a rigidbody. ideas?

Rigidbody is the class, rigidbody is the instance.

You want the instance.
