Logging in as administrator

[OJ-ROTEX095]

Hi. I tried out your code and it was interesting but when I went to the login as administrator field, after typing "admin@gmail.com" and password as "1234". It just showed some codes.

        <script>
            alert('Wrong Emailid or Password!!Please Try Again');
            window.open('../service-pages/admin-login.html', '_self');
        </script>
