OnTriggerEnter not being called, have trigger, RB, and colliders set?

Hi!

I have a GameObject that is supposed to set a boolean on its animator to true once a trigger is called. Thing is, I debugged it with print() and found that it was never called? Both the objects have 3D colliders, and one of them has a rigidbody. I have the object that needs to be collided with set to trigger. I triple-checked that my trigger Gameobject's tag is spelled correctly as well. I am lost on what I could be missing. Please help? Thanks.

Here is the code for the trigger.

     void OnTriggerEnter(Collider other)
     {
 
         if(other.gameObject.tag == ("PlayerAttack"))
         {
         health = health - 40;
         print(health.ToString());
         if(health > 0)
             {
             Anim.Play("GhostLightHit");
             Anim.Play("GhostIdle");
             }
         else if(other.gameObject.tag == ("EnemyTarget"))// The script part that isn't working
             {
             print("Collided");
             Anim.SetBool(Attacking, true);
             Anim.SetBool(canMove, false);
             Audio.clip = otherClip[Random.Range(0,otherClip.Length)];
             
             }
         else
             {
             Instantiate(GhostDead, transform.position, transform.rotation);
             Destroy(gameObject);
             }
         }
     }
