[AJAX][PHP] Formularz kontaktowy, Mail form Opcje

[kulfi89]

Witam,
Znalazłem ciekawy, a zarazem prosty formularz kontaktowy. Problem w tym, że pomimo wykonania wszystkich wskazówek z tutoriala nie wysyła maila. Stawiam swoje pierwsze kroki w PHP, stąd moja prośba o pomoc. Otrzymuję taki komunikat: "Uncaught TypeError: Cannot read property 'childNodes' of undefined". Poniżej wkleiłem (moim zdaniem) problematyczną część.

<div id="contactFormArea">
         <form action="scripts/contact.php" method="post" id="cForm">
         <fieldset>
                <label for="posName">Imię</label>
                <input class="input" type="text" size="25" name="posName" id="posName" /><br />
 
                 <label for="posEmail">Email</label>

                 <textarea cols="50" rows="5" name="posText" id="posText" class="textarea"></textarea><br />

          </fieldset>
