Bonjour,

Notre site intranet est relié à une base de données Access, et est hébergé sur Windows 2000 Server et IIS 5.0. J'ai voulu changer la taxe de vente pour le nouveau taux en vigueur depuis le 1er janvier, et en voulant tester le code sur une nouvelle facture "test", j'obtiens ceci:

Puisque l'erreur a été rapportée après que j'aie modifié le fichier .asp avec le nouveau taux de taxe, j'ai restauré le fichier à partir d'un backup récent, et ensuite j'ai redémarré le site Web, mais j'ai le même problème. Il y a donc une ligne de code qui ne passe plus, mais je n'arrive pas à trouver laquelle.

J'ai mis en rouge la valeur que j'ai modifiée (c'était 0.06 avant). C'est sûrement un truc banal, mais puisque je n'ai pas touché au développement Web depuis des lustres... Quelqu'un a-t-il une piste à me suggérer? Merci à l'avance.
