CR 10.2 - Is this correct syntax?

[blakemckenna]

I have a Crystal Report 10.2 that' I'm running with VB.Net 2005. My formula looks like this:

{tblTimeSheetDetail.beginPeriodDate} = '4/9/2007' AND 
{tblTimeSheetDetail.beginPeriodDate} = '4/23/2007' AND 
{tblTimeSheetDetail.beginPeriodDate} = '4/16/2007' AND 
{tblTimeSheetDetail.project} = '2006SC013'

I was wondering if this is correct syntax because I'm not getting any results on my report when I SHOULD be. The beginPeriodDate column is a String Type within my Table.

Thanks,
