Unity 5 Error Script :(

Hello,
Sorry 2 trouble all, But myself and my mate are new to unity... We trying to make it so when player walks into door it triggers to open: We have made this script:

Code (CSharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class Door : MonoBehaviour
6. {
7.     public AudioClip open, close;
8.  
9.     void onTriggerEnter(Collider Player)
10.     {
11.         if (Player.transform.tag == "Player")
12.         {
13.             GetComponent<Animation>().play("Open");
14.             AudioSource.PlayClipAtPoint(open, new Vector3(0,0,0));
15.         }
16.     }
17.  
18.     void OnTriggerExit(Collider Player)
19.     {
20.         if (Player.transform.tag == "Player")
21.         {
22.             StartCoroutine ("ExitTimer");
23.         }
24.     }
25.  
26.     IEnumerator ExitTimer()
27.     {
28.         yield return new WaitForSeconds(2);
29.         GetComponent<Animation>().Play ("Close");
30.         AudioSource.PlayClipAtPoint(close, new Vector3(0,0,0));
31.      
32.     }
33. }
34.  

But i'm getting these errors:
Door.cs(14,14): Error CS0117: 'UnityEngine.Animation' does not contain a definition for 'play' (CS0117) (Assembly-CSharp)
&
Door.cs(29,29): Error CS1061: 'UnityEngine.Animation' does not contain a definition for 'play' and no extension method 'play' accepting a first argument of type 'UnityEngine.Animation' could be found (are you missing a using directive or an assembly reference?) (CS1061) (Assembly-CSharp)

I'm using unity 5 btw. If anyone can help me fix this it will be great,
Thank you very much
Luke

 

"GetComponent<Animation>().play("Open");" needs the play to have a capital P.
