Hi John,

First, you are totally right about my cross post. It is the first time I was posting in this forum (and also in MS Office one), if my recollection is accurate. So, sorry for that mistake and it won't happened again (except if I put a note similar to the one you added at the bottom of my post).

Second, thank you so much for your help. Your answer sounds maybe very basic for your and most of this forum members, but I am a newbie. A newbie ready to learn.

Thank you again.

Vincent
