BCE0044: expecting EOF, Found 'var'

Hi, I can't find a mistake in this script, maybe you can help me out here. It's a simple melee script. Thank you

 var : TheDamage : int = 50;
 var : Distance : float;
 
 function Update ()
 {
     if (input.GetButtonDown("Fire"))
     {
         var hit : RaycastHit;
         if (Physics.Raycast (transform.position, transformDirection(Vector3.forward), hit))
         {
             Distance = hit.distance;
             hit.trasnform.SendMessage("ApplyDamage", TheDamage, SendMessageOptions.DontRequireReceiver);
         }
     }
 }
