Help with PlayFab Login Script

I have the following error: error CS1503: Argument 3: cannot convert from 'method group' to 'Action<PlayFabError>'. Line (60,69). I'm new to this and I have been trying but I can't fix it. If anyone can help, please.

Code (CSharp):

2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5. using PlayFab;
6. using PlayFab.ClientModels;

33.       bs = x.ComputeHash(bs);
34.       System.Text.StringBuilder s = new System.Text.StringBuilder();
35.       foreach(byte b in bs){
36.         s.Append(b.ToString("x2").ToLower());
37.       }
38.       return s.ToString();
39.     }

41.   public void SingUp(){
42.     var registerRequest = new RegisterPlayFabUserRequest{Email = userEmail.text, Password = Encrypt(userPassword.text), Username = username.text};
43.     PlayFabClientAPI.RegisterPlayFabUser(registerRequest, RegisterSuccess, RegisterError);
44.   }
45.  
46.  
47.

56.   }
57.  
58.   public void LoginIn(){
59.     var request = new LoginWithEmailAddressRequest {Email = userEmailLogin.text, Password = Encrypt(userPasswordLogin.text)};
60.     PlayFabClientAPI.LoginWithEmailAddress(request, LoginInSuccess, LoginInSuccess);
61.   }
62.  
63.  
64.   public void LoginInSuccess(LoginResult result){
65.     errorSingUp.text = "";
66.     errorLogIn.text = "";
67.     StartGame();
68.   }
69.  
70.  
71.   public void LogInError(PlayFabError error){
72.     errorLogIn.text = error.GenerateErrorReport();
73.   }
74.  
75.   void StartGame(){
76.     startPanel.SetActive(false);
77.     HUD.SetActive(true);
78.   }

Thank you, it was LogInError instead of LoginSucces. Anyway now it compiles without errors, but the scrip itself doesn't work I don't know why.
