Strange MissingComponentException while everything looks ok

I just started creating my first game using Unity and I already stucked. I tried to animate a mace and run the animation when the left mouse button is clicked, but I'm getting t$$anonymous$$s strange error:

 MissingComponentException: There is no 'Animation' attached to the "Mace" game object, but a script is trying to access it.
 You probably need to add a Animation to the game object "Mace". Or your script needs to check if the component is attached before using it.
 UnityEngine.Animation.Play (System.String animation) (at C:/BuildAgent/work/d63dfc6385190b60/artifacts/EditorGenerated/Animations.cs:569)
 MeleeSystem.Update () (at Assets/MeleeSystem.js:11)

Reffering to t$$anonymous$$s script:

 #pragma strict
 
 var theDamage : int = 50;
 var Distance : float;
 var maxDistance : float = 1.5;
 var TheMace : Transform;
 
 function Update (){
 
 if(Input.GetButtonDown("Fire1")){
     TheMace.animation.Play("Attack");
         var $$anonymous$$t: RaycastHit;
 
         if(Physics.Raycast(transform.position, transform.TransformDirection(Vector3.forward), $$anonymous$$t)){
             Distance = $$anonymous$$t.distance;
             if(Distance < maxDistance ){
                 $$anonymous$$t.transform.SendMessage("ApplyDamage", theDamage, SendMessageOptions.DontRequireReceiver);
             }
     }
 }
 }

Where line 11 is: TheMace.animation.Play("Attack");

I have done everyt$$anonymous$$ng as it shoud. Here is a screenshot of my workspace:

Where:

1) is the Melee - you can see that the Mace is a c$$anonymous$$ld of it. 2) the Melee script. 3) TheMace variable is assigned correctly.

I know that I miss a small part here, but as a complete beginner, I just can not spot it. Can you give me a push?
