I am a new programmer, and I am getting errors on my program which is a login and registration system, I am also trying to pass values between the registration and log in form, I would appreciate any help ;) here is the errors I get: There is no argument given that corresponds to the required formal parameter of 'passvalue' of Form2.Form2(string)
There is no argument given that corresponds to the required formal parameter of 'password' of Form3.Form3(string)
There is no argument given that corresponds to the required formal parameter of 'password' of Form3.Form3(string)

What I have tried:

public partial class Form3 : Form
    {
        public string username,password,repassword;
      
        public Form3(string password)
        {
            InitializeComponent();
            password = textBox2.Text;
 

        }

       

        private void button1_Click(object sender, EventArgs e)
        {
            string password = textBox2.Text;
            string username = textBox1.Text;
            string repassword = textBox3.Text;
            if (password == repassword)
            {
                MessageBox.Show("Successfully Registered");
                Form2 newwin = new Form2();

                Form3 newwindow = new Form3();
                this.Close();
                newwin.Show();
            }
            else
            {
                MessageBox.Show("Passwords Do Not Match OR Not All Required Fields Filled");
                this.Close();
                Form3 newwindow3 = new Form3();
                newwindow3.Show();
            }
            Form2 passvalue = new Form2(password);
