[AccessD] trying to filter a form on a control's value

That's what I thought Jim. As I wrote, since this filter doesn't reapply
itself the way a control source would, I gave up on filter.

To better explain, what I really wanted was a filter to be formulaic. But
it never is, it can be set US ING a formula,  but it is always going to be
a fixed string.

By contrast, a controlsource is also a string but Access recomputes what it
should display - and can be set to depend on a function or another control.
A filter apparently doesn't do those kinds of things, I was just using
wishful thinking.
