Force instead of manipulation

Heres my attempt at moving my submarine by force

var forwardspeed=100;
var sidespeed=100;
var turnpower=100;

function FixedUpdate () {
   rigidbody.AddRelativeForce (0, 0, (forwardspeed * Input.GetAxis("Vertical")));
  rigidbody.AddRelativeForce (0, 0, (sidespeed * Input.GetAxis("Horizontal")));
       rigidbody.AddRelativeTorque (Vector3.up*turnpower * Input.GetAxis ("Mouse X"));
        }

Im getting something from the third line but not the first two…
What is the key here? Im just getting feet wet here. I cant wait till I get good enough at this to put all that high school physics to work
Cheers
