Hello everyone,

I am new to this forum. I hope I get something out of this. I am very new to crystal report 8 and build and customize few reports. Now, I am stuck in between my modifying open order by customer report. My questions is "How do I right formula in select expert that pulls all data when date field is blank?" Here's what I did so far.

1) I created new parameters = fromdate and todate.
2) I put that parameters inside the report.
3) I selected that field in a select expert and added a formula in formula editor.
4) The formula goes something like this;
             {Orderdates.Releasedate} in {?fromdate} to {?todate}
With this formula it only pulls data between that range but when I leave it blank it shows error message. Please advise me to a right path.

Thanks,
Brijesh

Yes I want to pull all dates when you leave the field blank.
