    I am a begginner at html and javascript, I have this problem for class and I cannot figure it out, I know it must be something simple. I am trying to create a page that has a form, if you do not fill out the form when you press submit I want an error message to tell you it cannot be submitted you did not fill out the form.

    <!DOCTYPE html>
    <html lang="en">
    <head>
    <title>JavaScript Practice</title>
    <meta charset="utf-8">
    <script type="text/javascript">

    <!-- function validateForm() {
    if (document.forms[0].userName.value == "" )
    { alert("Name field cannot be empty.");
    return false; } // end if alert("Name and age are valid.");
    return true; } // end function validateForm // -->

    </script>
    </head>

    <body>
    <h1>JavaScript Form Handling</h1>
    <form method="post" action="http://webdevfoundations.net/scripts/formdemo.asp"
