Below is the data set that I'm using as the drop down list for the Name parameter.
The user would like to be able to select multi values or NULL value for the Name.
In the parm properties, I selected 'allow blank values' and 'allow multiple values'.
When I viewed the report, the drop down list only display Name with values.
How can I have the NULL display in the drop down list so the user can select record with NULL name?

NULL NULL
NULL 1
