Please keep in mind that "blank" means something different to humans than to
Access. If you look at a field or control and don't see anything, you count
that as "blank", right?
But Access distinguished among three possibilities ... 1. nothing is there
==> Null; 2. a zls (zero-length string, "") is there ==> ""; 3. some
number of "space"s are there ==> e.g., " "
You probably can't tell the difference by looking, but Access won't consider
#2 or #3 if you tell it to look for #1.
