Hasvalve() function isn't working properly [Crystal Reports 2008]

[Former Member]

Hello:

I am using a record selection formula which includes both a start date and end date parameters. Currently using HasValue() to determine if either the start date or end date is null. Both dates are "Optional" prompts. I can't get the report to run if either one of the dates is null. How can I get around this?

(not HasValue({?START_DOCUMENT_REC_DATE})) OR ({QAS.DOCUMENT_REC_DATE} in {?START_DOCUMENT_REC_DATE} to {?END_DOCUMENT_REC_DATE})
