Dear Gabriel, I hope I have met your requirements, although they were very interpretable. Let say that I hope I have well understood... :-) Now is late in Italy and I have to stop my work. I know the contest finish in a couple of hours, and after that I will not upload anything. Only the winner will do. Anyway it was a pleasure work for you. Have a great fortune with Moblity. It's really a good name. Best regards from Italy. sergio
