XHTML 1.0 valide mais mes formulaire marche plus...

voici mes formulaire: ( sur www.midicom.fr )

<form id="formNews" name="formNews" action ="creerCompte.php" method="post">
<input onclick="reset_newsletter('blanc')" name="newsMail" type="text" value="Votre e-mail" size="14" />
<input type="submit" name="news_ok" value="Ok" />
</form>
et

<form id=\"formCompte\" name=\"formCompte\" action=\"$loginFormAction\" method=\"post\">
<input onclick=\"reset_login('blanc')\" name=\"login\" type=\"text\" value=\"Login\" size=\"11\" /><br />
<input type=\"password\" name=\"password\" value=\"password\" size=\"11\" />
<input type=\"submit\" name=\"compte_ok\" value=\"Ok\" /><br />
<div style=\"font-size: 10px; font-weight:normal;\">
<a href=\"mdp.php\">(J'ai perdu mon passe)</a>
</div>
</form>

Mes deux formulaire vont à la bonne page mais ne reponde plus. il n'envoie pas les données on dirait... par exemple avec de mauvais identifiant je devrais rester sur l'index avec ecrit: mauvais identifiant.

je suis perdu.

Voici le code de ma page si sa peut aider:
