Perhaps I'm slipping into senility. I felt certain I'd asked this here
before, and got it answered. Not only do I not remember the definitive
answer, I can't find in searching thelist archives.

In a form response page, how do I test for the existence of a form field
value being passed from the form? I don't care what the value is, I just
want to know if there *is* one. I've played with IsNull and IsEmpty,
played with > comparison strings, and nothing seems to give reasonable

Thanks. Again.
