Crystal Reports Null Fields

Hello,
      I have a Crystal report that uses a date field to pull data. I have this report field selecting by “less than or equal to” a date I have decided was a workable date. However, some of these date fields are null. How do I tell the report to keep using the “less than or equal to” date as well as if it is null? What I mean is that I would like to show both the “less than or equal to” and null items.

Thank you

Remember NULL is the ABSENSE of a value.  It is not a value and cannot be compared.
When Crystal encounters a NULL it terminates the evaluation and the result is indeterminate.

Instead you have to test for it.

Try this

(
   IsNull({YourDatefield})
   OR
   {YourDatefield} <= {?DateParameter}
)
