attack animation array

have a nice enemy behaviour script that works fine but it only has a single attack. I want to add an array that randomly plays. Looked at example in the forums but can't get them to work for me. won't paste the whole script just the parts where the changes would be made

 public enum EnemyState{IDLE = 0, WALK = 1, RUN = 2, ATTACK = 3, KILL = 4};
     public AnimationClip enemyIdle;
     public AnimationClip enemyWalk;
     public AnimationClip enemyRun;
     public AnimationClip[] enemyAttack;     //attacking player
     public AnimationClip enemyKill;
     public AnimationClip enemyDie;
 
 //Above I added the animation array to enemyAttack. then mid script is the below code that if within striking distance go to the Attack function
 
 if (Vector3.Distance (transform.position,Player.position) < MinDist)
         {
             currentState = EnemyState.ATTACK;
             Attack ();
 
 //_________________________________________________
 //then , in the Attack function is where I am trying to have the array
 
 public void Attack()
     {
         
 enemyAttack[Random.Range(0,enemyAttack.Length)];
