CR 2008 - Allowing BLANK value as Dynamic Parameter option

I recently upgraded to Crystal 2008 from Crystal XI.
I have a report that has a Dynamic Parameter that allows all distinct values from a table to be available to select; One of the values was an actual blank value.

We need to be able to report by selecting the blank value. I don't want to set the parameter as Optional and return all values, I want to be able to run the report for JUST the blank values.  It appears Crystal 2008 just ignores blanks and doesn't allow you to select them as an option with a dynamic parameter.

Is there some setting that I can flip to allow a Blank value in the Dynamic Parameter?

Hi Chris,

CR doesn't allow blank values in a dynamic prompt.

Please have a look at the second option from my reply in this thread:

Parameter option for Is Null
