Well it's quite clear, isn't it? SignInScreen() takes four parameters You call SignInScreen() with zero parameters

I tried copying all the parameters as well before, didn't make a difference but gave me 10x errors. Can you show me a corrected example? Because for me, it isn't quite clear unfortunately.

If a method takes parameters, method must get parameters

public string GetSum(int a, int b)
{
    return $"Sum of {a} and {b} is {a + b}";
}

string result;
result = GetSum(); // bad
result = GetSum(10, 2); // good

public string GetSum(int a, int b)
{
    return $"Sum of {a} and {b} is {a + b}";
}

string result;
result = GetSum(); // bad
result = GetSum(10, 2); // good

So, see if you even need those parameters From what I can see in your code, you don't use any of them in the method

Oh I left them there for future use, ah well to remove it for now Thanks I think I get it now

btw don't use Convert.ToInt32. use int.Parse or (preferably) int.TryParse instead. You can directly replace Convert.ToInt32 with int.Parse so you should do that, but in order to use int.TryParse you would have to make a few additional changes also you can replace

Console.WriteLine(" --------- \n Login Screen \n ---------");
Console.WriteLine(" 1. Sign up \n 2. Sign in \n 3. Exit");
Console.WriteLine(" Note: Enter the number to choose" +
    "your function throughout the program");
Console.Write(" Choose your function: ");

Console.WriteLine(" --------- \n Login Screen \n ---------");
Console.WriteLine(" 1. Sign up \n 2. Sign in \n 3. Exit");
Console.WriteLine(" Note: Enter the number to choose" +
    "your function throughout the program");
Console.Write(" Choose your function: ");

with

Console.Write("""
     ---------
     Login Screen
     ---------

     1. Sign up
     2. Sign in
     3. Exit

     Note: Enter the number to choose your function throughout the program

     Choose your function: 
    """);

Console.Write("""
     ---------
     Login Screen
     ---------

     1. Sign up
     2. Sign in
     3. Exit

     Note: Enter the number to choose your function throughout the program

     Choose your function: 
    """);

much cleaner in my opinion

Holy shiiiii that seems so useful I dont think I ended up fixing anything, uh Im getting more confused Can someone show me a corrected example of this just so I can understand where I went wrong Been stuck here for a while uhh

This method

static void SignInScreen(string name, string password, string phoneNumber, string email)

static void SignInScreen(string name, string password, string phoneNumber, string email)

takes four parameters Here you call this method

else if (loginInput == "2")
    SignInScreen();

else if (loginInput == "2")
    SignInScreen();

but you give it zero parameters

Was this issue resolved? If so, run /close - otherwise I will mark this as stale and this post will be archived until there is new activity.
