Mouse Look Help

When ever I move my mouse up the screen goes down. When I move my mouse down my screen goes up. I would like it so that when I move my mouse down my screen goes down with it. If you could fix it that would be lovely. Thank You!

Here is the code:

 var lookSensitivity : float = 5;
 private var yRotation : float;
 private var xRotation : float;
 private var currentYRotation : float;
 private var currentXRotation : float;
 private var yRotationV : float;
 private var xRotationV : float;
 var lookSmoothDamp : float = 0.1;
 
 function Update () {
     yRotation += Input.GetAxis("Mouse X") * lookSensitivity;
     xRotation += Input.GetAxis("Mouse Y") * lookSensitivity;
     
     xRotation = Mathf.Clamp(xRotation,-90,90);
     
     currentXRotation = Mathf.SmoothDamp(currentXRotation,xRotation,xRotationV,lookSmoothDamp);
     currentYRotation = Mathf.SmoothDamp(currentYRotation,yRotation,yRotationV,lookSmoothDamp);
     
     transform.rotation = Quaternion.Euler(currentXRotation,currentYRotation,0);
 }
