I'm having a problem with getting a door to open

I don't know javascript, but I would try something like this:

1. on the door gameobject, check the "isTrigger".

2. make sure that your player's name in the Hierarchy is "Player"

3. Go to Edit>Player Input> make a new one by changing the number of inputs. Title it "Action", and make the positive button 'e'. This may even fix the problem entirely. Change the KeyCode.E to "Action". If this fixes it, ignore everything else.

4. Attach this script to the door:

TIPS: If there is any error in the script, find the line that has the error. If the line with the error has one "=" add another one after it. If it has two, remove one.

 using UnityEngine; 
 using SystemCollections; 
 
 public class doorOpen : Monobehaviour {
 
     public AnimationClip liukuoviClip; 
     private bool isOpen = false; 
 
     void Start () {
         
     }
     
     void Update () {
         
         if (isOpen == true) {
             liukuoviClip.Play(); 
         }
     }   
     
     void OnTriggerStay (Collider other) {
         if (other.gameObject.name == "Player") {
                    if (Input.GetButtonDown("Action")) {
                        isOpen = true; 
             }
         }
     }
 }
