animation dose't play in scene

I have made a small animation and attached it to an object in the scene the I attached a small script to that object to play the animation.
however, when I try it out it gives me this error message

this is my code

Code (csharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class startAnim : MonoBehaviour {
5.  
6.     // Use this for initialization
7.     void Start () {
8.        
9.     }
10.    
11.  
12.     // Update is called once per frame
13.     void Update () {
14.  
15.             animation.Play();
16.  
17.     }
18. }

and this is a screen shot of the object with the animation and code attached with it

 

animation is the legacy animation system. You're using Mecanim. Try Animator animator = GetComponent<Animator>();

Then you can do animator.Play("close_hand_a");

Animation = Legacy
Animator = Mecanim

Also note when you import your models, you have to import them using the Mecanim setting and setup the avatar target system.
