Collision detection with tag not working

I'm trying to use the following code:

Code (CSharp):

1. void OnTriggerEnter(Collider other) {
2.         Debug.Log("We hit something!");
3.         if (other.gameObject.tag == "Player" && other.gameObject.GetPhotonView().owner != gameObject.GetPhotonView().owner || other.gameObject.tag == "Zombie") {
4.             other.gameObject.GetComponent<Health>().TakeDamage(25);
5.             Debug.Log("We hit a zombie!");
6.         }
7.  
8.         if (other.gameObject.tag == "Zombie") {
9.             Debug.Log("Zombie");
10.         }
11.         //We didn't hit ourselves. Destroy the bullet.
12.         if(other.gameObject.GetPhotonView().owner != gameObject.GetPhotonView().owner) {
13.         PhotonNetwork.Destroy(gameObject);
14.         }

The only part that seems to work is it'll detect when it "We hit something!" but the tag detection isn't working. Any ideas? The gameObjects im colliding with are properly tagged.
