Unknown Error! PLZ HALP!!11

I am trying to make a "Button" that will open a door in a 2d enviroment. I get an error on the triggerScript saying "the associated script can not be loaded. please fix any compile errors and assign a valid script" I have made a sprite called TriggerObject that has the triggerTrigger script bellow.

 using UnityEngine;
 using System.Collections;
 
 public class triggerTrigger : MonoBehaviour
 {
     public static bool isTrigger = false;
 
     public void OnTriggerEnter2D(Collider2D other)
     {
         if (isTrigger == false)
         {
             Debug.Log("Collided!");
             isTrigger = true;
         }
     }
 
     public void OnTriggerExit2D(Collider2D other)
     {
         if (isTrigger == true)
         {
             Debug.Log("Exit!");
             isTrigger = false;
         }
     }
 }

Ive also got a door called Door1 with the script down below

 using UnityEngine;
 using System.Collections;
 
 public class Trigger : MonoBehaviour
 {
     Vector3 tempPos;
 
     public void Start()
     {
         GameObject triggerObject = GameObject.Find("TriggerObject");
         triggerTrigger TriggerTrigger = triggerObject.GetComponent<triggerTrigger>();
         Debug.Log("TRIGGER INITIALIZED");
     }
 
     public void Update()
     {
         if (triggerTrigger.isTrigger == true)
         {
             Debug.Log("MOVING");
             tempPos = transform.position;
             tempPos.y -= 0.05f;
             transform.position = tempPos;
         }
             
     }
 }
 

If i could get some advice, that would be perfect!
