Dialouge isnt working

Hey! as the title said im trying to make a game where it pops up a dialouge when i start the game. But when i press the buttons nothing happens. i have put in the OnClick() on the button objects. it seems to be a problem with the buttons because the load scene thing isnt working either. The public strings is probably not needed? but it looks cool my script:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.UI;
 using UnityEngine.SceneManagement;
 public class Talk : MonoBehaviour {
 
     public GameObject DialougeObj;
 
     public Text Question;
     public Text Answear1;
     public Text Answear2;
     public Text Answear3;
 
     public string QuestionString;
     public string Answear1String;
     public string Answear2String;
     public string Answear3String;
 
    
     void Start()
     {
         Answear3.gameObject.SetActive(false);
         QuestionString  = "Do you want to play the tutorial?";
         Answear1String = "Yes!";
         Answear2String = "No!";
 
     }
 
     void Update()
     {
         Question.text = QuestionString;
         Answear1.text = Answear1String;
         Answear2.text = Answear2String;
         Answear3.text = Answear3String;           
     }
     public void Answear1Butt()
     {
         Answear2.gameObject.SetActive(false);
         Answear3.gameObject.SetActive(false);
 
         QuestionString = "Use WASD to move" +
             "1 for pistol, 2 sword, 3 for weapon3" +
             "Easy right?, now play the tutorial map and then through the portal!";
 
 
         Answear1String = "Yes, sir!";
     }
 
     public void Answear2Butt()
     {
         DialougeObj.SetActive(false);
         SceneManager.LoadScene("Main World");
     }
 
 
 
 }
