Awesome! The fix worked like a charm ;)
Thank you very much Niphlod, I really appreciate your help, you're
definitely a wise "web2py guru".
I've been always grateful for the help received here. I really want to give
something back, but then I read the questions posted, and I really can't
find one that I could answer with precision :P
Anyway, thanks again. Let me know if I have to submit a ticket or something
like that.
