Hope this helps,

Thank you very much Marteen,
definitely this helps.
Still, I really would like to undertsand why my code does not work...
it would be better to me keep the things simple and straightforward when we go
for code.
Anyway, I will study and try to adpat your example to my needings, thank you again
Diego
