Loading new form has a error in if statement?

i keep getting a error when trying to load a new form on my if statement? at the end of the frm.show();

 if (listBox1.FindString(metroTextBox1.Text) != -1)
            if (listBox2.FindString(metroTextBox2.Text) != -1)
                MessageBox.Show("Found it!");
        Form2 frm = new Form2();
        frm.Show();



        else
        {
        MessageBox.Show("TRY AGAIN");
        }
