it syas expected. insert a semicolan at the end were do i insert it??

#pragma strict

var rotationSpeed = (100);

function Update ()
{
var rotation : float = Input.GetAxis (“Horizontal”) * rotationSpeed;
rotation *= Time.deltaTime;
(AddRelativeTorque)(Vector3.back * rotation);
}

remove parentheses from the value of rotationSpeed

var rotationSpeed = 100;

apply asterisk in this line

var rotation : float = Input.GetAxis ("Horizontal") * rotationSpeed;

and i don’t know what this line is trying to do

(AddRelativeTorque)(Vector3.back * rotation);
