Thomas,
Your question isn't quite clear to me. If you want business dates, why
do you want to include Saturdays & Sundays (in my part of the world at
least, not business days)? Perhaps I am misunderstanding your
question. In general, it is advisable to give a _short_ example of
what you have presently and what you would like to acheive.
Regards,
Rebecca
