Dear Gradius, You deserve my deepest regards and thanks for the help you posted here. It worked perfectly with no problem. I joined this forum, only to thank you. I found this topic by google search engine. It is very simple and perfect indeed. I would like, please, to exchange more information. I don´t know how to contact you in this forum, I am new to this kind of mechanisms. It is always an honor to learn with the "humble" professionals who believe in sharing knowledge. Thank you very much, My best regards, Toni
