script pour un bot

Bonjour,

Je souhaite afficher sur une page un bot (j'utilise pour cela le logiciel libre Program-O). Voici la page complète, avec du Javascript pour rafraichir uniquement la div de conversation :

La page s'actualise bien et affiche ce que le visiteur tape, mais le problème c'est que je n'arrive pas à afficher la réponse du bot. Y a-t-il un moyen de tester l'envoie de données entre la page HTML et la page PHP, et vérifier le retour ?

Si quelqu'un pouvait me renseigner svp, merci d'avance,
Très cordialement,
