Script copied exactly, yet I get the console errors

I am doing this tutorial on making a sphere on a long rectangle jump by pressing the W key, and I can roll the ball using A or D. This is the 2nd time I’ve followed one of this guys tutorials which produce console errors for me and not for him. Here is a screenshot of his code on youtube:

And here is my code, followed by the Unity console error:

#pragma strict

var rotationSpeed = 100;
var jumpHeight = 8;

private var isFalling = false;

function Update ()
	//handle ball rotation
	var rotation : float = Input.GetAxis ("Horizontal") * rotationSpeed;
	rotation *= Time.deltaTime;
	rigidbody.AddRelativeTorque (Vector3.back * rotation);
	if (Input.GetKeyDown(KeyCode.W))
		rigidbody.velocity.y = jumpHeight;

And error:

What gives???

Functions are opened and closed with squigglies { } instead of parens ( ), same with if blocks
