How to create a rule that checks for a blank value in the DB
I'm trying to create a security assist rule to display an area on a page if a database field is found to be blank, but I'm not having much success.
I have been using Rule Manager and I created a rule to compare the value of the database field held in a recordset and set the criteria to be <> '' (that's two single apostrophies), but it's not working.
Do I have to leave the compare to field itself blank in rules manager to get this type of validation to work??
