Door doesn't open but closes...

This is in Unity 5
Hello,
I'm not the best at coding (Prob why its not working )... My mate helped me work on this, But i have done this video to show u want it's doing for me;

When "Player" goes into Trigger... The door doesn't open but when you come out of the trigger the Animation starts from Open to Closed. Is the code wrong or have i done something wrong? How i made the Animation for the doors were copy the door 2 times add open Animation to 1 and close to the other then remove them.

The code can be found here:

Code (CSharp):

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

If you can help be great
Thank you

 

onTriggerEnter should be OnTriggerEnter (capital O).
Hint: When it's not highlighted in red then there must be a typo.

 

Thank you very much!
