Hello JérômeP,

Thank you for taking over from me to answer Aurélien while I was on vacation. In addition, notifications of new posts don't seem to work for me anymore so I wasn't going to answer.

M.

PS: Aurélien, if Jerome's macro works well, could you select his answer as the best answer? This is to close the discussion thread.
