Is there anyway to conduct a NOT NULL test on a field? So in the Condition dialog "If this field is NOT NULL then ..."
"Not Equal to Custom Value <empty>" did not work (where <empty> means nothing entered)
Reason: I want to show the following 2 fields only if the current field has a selected value. I don't want to use "Equal to" because that would not work for a database query field - values might change.
