What is wrong with my script for Opening a door on click

using UnityEngine; using System.Collections;

public class DoorOpener : MonoBehaviour {

 private bool doorOpen = false;
 private float animationFinished = 0;

 void Update (){
 if (Input.GetMouseButtonDown (1))

 {


     Debug.Log ("Ive been clicked");

     if(Time.time > animationFinished)
     {
         if(doorOpen)
         {
             animation.Play("Door Close");
         }
         else
         {
             animation.Play("Door open");
         }

         animationFinished = Time.time + 1;
         doorOpen = !doorOpen;
     }
 }

} }

I am getting these errors when I try to use the above script

Assets/DoorOpener.cs(25,15): error CS1061: Type UnityEngine.Component' does not contain a definition for Play' and no extension method Play' of type UnityEngine.Component' could be found. Are you missing an assembly reference?

Can someone please explain what is wrong
