Undefind tag?

So ive been using unity for about 2 weeks now with no problems what-so-ever in any of these 2 scripts. But after editting a bit of code today that had to do with damage rates(It shouldnt have effected the tag system at all) I am getting a "GameObject has undefined tag!" Error in 2 of my scripts that check tags. All of my gameobjects have tags.So i have no idea what the problem could be?

SCRIPT 1:

     void shoot(int Damage,int Range){
             /*
             Direction=transform.FindChild("Armature").forward;
                     float Offset=.1f;
                     Direction.x+=Random.Range(-Offset,Offset);
                     Direction.y+=Random.Range(-Offset,Offset);
             */
             if(Physics.Raycast(transform.position,transform.FindChild("Armature").forward, out hit,Range) && canShoot){
                 if(hit.transform.tag==("Zombie") && hit.transform.GetComponent<Health>()!=null && hit.transform.GetComponent<Health>().dieID==2){
                     hit.transform.GetComponent<PhotonView>().RPC("takeDamage",PhotonTargets.AllBuffered,Damage);
                 }
                 Debug.Log("HIT: "+hit.transform.tag.ToString());
                 drawRays=true;
             }else{
                 drawRays=false;
             }
         }

I get a error on the if statement involving the Zombie tag.

And in SCRIPT 2:

 void OnTriggerEnter (Collider col){
 
         if(col.transform.tag=="Player" && !triggerLocked && PhotonNetwork.isMasterClient){
             target=col.gameObject;
             triggerLocked=true;
             }else if( col.transform.tag == "Untagged" ){}
 
 
     }

I get a error checking the Player tag.
