enum not referencing properly

So I have an attack script and a character controller script. I have an enum in my character controller script for basic animations (run, jump, fall etc.) and I have animations in my attack script such as jab. Here is my enum for my character controller script:

 public enum State { idle, running, jumping, falling }

here is the way I referenced my enumerator:

 if (ahmadcontroller.state == Ahmadcontroller.State.idle)
         {
             animator.SetTrigger("cross");
         }
         else 
         {
             animator.SetTrigger("rcross");
         }

yet it isn't working. How do I fix this?
