Bonjour le forum

je sens que c'est tout bête, mais je ne vois pas

ma macro tombe en erreur "subscript out of range".

voici l'extrait de code qui plante:
Code : Sélectionner tout - Visualiser dans une fenêtre à part

Dim MonthList() As String
h = CStr(Year(Now())) + "-0" + CStr(X) ' qd l'erreur est rencontré, le résultat dans h="2013-02"
MonthList(k) = h ' et k=0
je dois louper qqc dans la syntaxe, mais je ne vois pas.

par avance merci pour votre aide

Ci-dessous, la macro en entier pour info:
