Help Please Debug A Script - Fixed!

Could someone good with Unity Javascript take a peek at this script and let me know if I am missing any brackets or other syntax. The errors Im getting in MonoDevelop are:
Expecting ( Found Fixed Update, ; expected at the end.
Unexpected token if
Unexpected token var
Expected EOF found }

/Arrow Turn Function
function FixedUpdate(){

if (Input.GetAxis("Turn")){
 
	var rotation : float = (Input.GetAxis("Turn")) * rotationSpeed * rotationSensativity;
	rotation = rotation + transform.eulerAngles.y;
	transform.localRotation = Quaternion.AngleAxis ( rotation, Vector3.up);
}

//Arrow Turn Function //See the notes below

    function FixedUpdate(){
    
    if (Input.GetAxis("Turn")){
    
        var rotation : float = (Input.GetAxis("Turn")) * rotationSpeed * rotationSensativity;
        rotation = rotation + transform.eulerAngles.y;
        transform.localRotation = Quaternion.AngleAxis ( rotation, Vector3.up);
        }
    }
    
    // Require a character controller to be attached to the same game object 

@script RequireComponent (CharacterMotor) 

@script AddComponentMenu ("Character/FPS Input Controller")

You used one / and a comment uses two /'s not one. I’m am sure that was an honest mistake.
