Hi, Edward

I'm sorry for my mistake : your question was nos so clear, as it was not a PBP Background ... I always think we are on a PBP Forum ...

Yes, I become a bit angry these times : reading here pages and pages of code with the same questions : where is my error or ( can you ) do it for me ??? or ground level Questions showing the manual ( humour ...) has never been opened, is RATHER BORING.

Regards
Alain
