Thanks to all for such prompt and detailed advice. A lot of it is a little
over my head at this stage, but I will plow (plough) through it all and see
what I come up with.
I don't want to come between Steve and Dennis, and am certainly not
authorized to comment, however I always try to start a journey with the end
in mind....it is the only way I know that I ever get there.
Sage advice however, on labeling techniques, so thanks to both. I will
continue to define what I want out of the system, then post more details of
the tables as I develop them.

And I will visit those tutorials!
Thanks again to all,
Roy.
