Thanks everyone for the replies and instruction.
I agree that there are better ways to layout the tables, but I'm sort of the guy
who gets handed the crappy poker hand while it's owner goes to the restroom and
is expected to make it a winner. :-) In other words, I really can't lay out the
tables the way I would've wanted to.
So, within those contraints Randal hit it right on the nose. I was definitely
not catching on enough to see that the 'NATURAL' option to the joins is an
obvious choice, which was part/all of my problem. Thanks Randal and everyone!
