Here is my Problem I have a Cascading lookup in my Nintex Form that works.  The problem is that for some of the selections when filtered there are no results.  I want to hide those lookup controls when empty but because of the default return value of a lookup (null) I can't get the rule to work.  If I use the Rule isnullorempty(Affiliation) or not(Affiliation) it will hide but will not unhide when required to enter more Choices. What am I doing wrong?
