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
