Syntax error: Instance required to access non static member

I keep getting this error: Assets/Standard Assets/Character Controllers/Sources/Scripts/MeleeSystem.js(11,40): BCE0020: An instance of type 'UnityEngine.Transform' is required to access non static member 'position'.

 #pragma strict
 
 var TheDammage : int = 50;
 var Distance : float;
 
 function Update ()
 {
    if (Input.GetButtonDown("Fire1"))
    {
         var hit : RaycastHit;
         if (Physics.Raycast (Transform.position, transform.TransformDirection(Vector3.forward), hit))
         {
             Distance = hit.distance;
             hit.transform.SendMessage("ApplyDammage", TheDammage, SendMessageOptions.DontRequireReceiver);
         }
    }
 }
