Thank You Samuel
what you say is what I expected to happen.....
But this was not in my previous tries .
Errors came for lack of experience, that bring doubt (and this is what is now happening to me)
Know what you wrote is important, because now I'll look elsewhere to solve my problem ...this can have another cause .
So I thank you for give me this certainly.:-)
