hit gameobject tag

I use a raycast in my gun script and if it $$anonymous$$ts a gameobject with the tagg zombie it has to send a message to that gameobject to apply damage I can send messages and detect if somt$$anonymous$$ng is $$anonymous$$t but it doesn't recognise the tag. here is my code to detect the $$anonymous$$t:

 if (Physics.Raycast(transform.position, fwd, 10)&& tag == Zomie) { 
          print("$$anonymous$$t");
         gameObject.Find("Zomie").SendMessage("ApplyDamage");
        }
