Script traitement formulaire

Bonjour,

J'ai créé un formulaire de contact et je voudraus traiter les données avec un script php et qu'une fenetre "merci" s'ouvre une fois le formulaire envoyé.

J'ai récupéré un script php de traitement mais je ne sais pas comment l'adapter en fonction de mon formulaire.

Voici le code de mon formulaire :

<form method=post id='Form1' name='Form1' action='http://www.cwsecretariat.fr/mail.php' onsubmit=FireEvent('Form1','_OnSubmit') onreset=FireEvent('Form1','_OnReset')>
<DIV id=CATEGORIE style="visibility:visible;overflow:hidden;overflow:visible;position:absolute;z-index:39;left:270;top:439;width:0;height:0;">
