Echec de mise a jour

Bonjour,



e rencontre un probleme innatendu. Apres avoir cree un formulaire qui contient des fonctions qui cachent et qui affichent des champs tout depend du choix du user dans un select. le formulaire marche comme voulu. Le probleme c'est que les variables ne sont pas recues dans une page pour effectuer un update dans la base de donnees.

voici les codes javascript

function changementType() {
   var type = document.getElementById("type").value;
   if (type == "Complete") {
       document.getElementById("Complete").style.display="block";
   } else{
       document.getElementById("Complete").style.display="none";
   }
   if (type == "NotFound"){
       document.getElementById("NotFound").style.display="block";
   }else{
       document.getElementById("NotFound").style.display="none";
   }
   if (type == "Start"){
       document.getElementById("Start").style.display="block";
   }else{
       document.getElementById("Start").style.display="none";
   }
}

Voici les codes du formulaire
