Quand j'excute, j'obtiens l'erreur suivante:

Citation:

La ligne qui pose problème est :

Citation:

intCIGAR[i] = aValCIGAR[i];

J'ai beau revoir le script plusieurs fois, je ne vois pas le problème.
La taille du tableau me semble correcte, mais comme je suis débutant, l'oeil d'un expert m'aiderait.

Merci.
