URGENT verification code formulaire

Slt les balaises,

cela fait plusieurs jours que je suis empetré avec un encodage de formulaire de contact. Je suis à bout de souffle tellement je peine à trouver la solution. Si une ame charitable veut bien jeter un coup d'oeil sur mon codage html et vérifier celui de la page php associée et me corriger les erreurs si possible. les programmes sont assez long et il faut patienter (c'est long mais facile à comprendre).
