Seems to me the only definitive way to distinguish whether a value was
passed (as opposed to a value of "" or Nothing being passed) would be
something like:

FOR EACH FieldName IN Request.Form
	IF FieldName = "TheFieldNameIAmLookingFor" THEN
		'Found it...if the loop completes without 
		'this code being run, it wasn't there.
	END IF
LOOP
