I have a group (county) which can have data or be empty. How can I change the group expression, to group data when group field is empty, and group matching criteria. Is there a way to add a second grouping to a group and change "IsEmpty" to true?
Test changing the field in the grouping using IIf (with Conditional Functions). Or one other thing - Fields(Parameters.Parameter1.Value) = group by the field name I pass as parameter.
