    <p>Here is the information that you entered: </p>
    <table cellspacing="5" cellpadding="5" border="1">
        <tr>
            <td align="right">First name:</td>
            <td><%= firstName %></td>
        </tr>
        <tr>

            <td align="right">Email Address:</td>
            <td><%= emailAddress %></td>
        </tr>
    </table>

    <p>To enter another email address, click on the Back <br />
    button in your browser or the Return button shown <br />
    below.</p>

    <form action="index.jsp" method="post">
        <input type="submit" value="Return" />
    </form>

</body>
</html>

and it's giving me this error page...
