How to Allow Blank Date Parameters in Crystal 11?

[thementornetwork]

I am supposed to create a report where the user can choose to use an "as of date" or a specified "date range".
As a result I set up 3 date parameters with IF NOT ISNULL validation.
However it seems like Crystal forces me to fill all 3 parameters when I try to preview the report. Anyway, I can allow date parameters to be blank or null? Thanks.

If the parameter is from a stored procedure you can set it to a NULL value, and then handle the NULL's there.

I'd set the report up with a start date and End date as separate parameters and most users should be able to handle that okay.

Thanks for your advice but that report isn't using a stored proc. What I ended up doing was to set up a default start date and default end date which I may or may not end up using based on some other conditions.
