On peut écrire la condition de plusieurs manières, la 1ère est la plus simple :
Code:
If Client <> "Jp Ma" And Client <> "Jp Mb" And Client <> "Jp Mc" Then
If Not (Client = "Jp Ma" Or Client = "Jp Mb" Or Client = "Jp Mc") Then
If Not Client = "Jp Ma" And Not Client = "Jp Mb" And Not Client = "Jp Mc" Then
