Assuming this is Access, then you will need something like this in the WHERE clause of your query:

WHERE DateInTheTable <= (CDate(Forms![NameOfForm]![NameOfDateField]) - 21)

tried that with this SQL not working

SELECT tblddai_renewalpostdate.daterenewalposted
FROM tblddai_renewalpostdate
WHERE (((tblddai_renewalpostdate.daterenewalposted)=([Forms]![frmDDAI_SB]![txtStartDate])-21));

Note you did not wrap the field in CDate() as shown by Patrick. Additionally, to be more explicitly in your intention, you may want to consider using DateAdd() (ref: http://www.techonthenet.com/access/functions/date/dateadd.php). It is better to explicitly convert to date using CDate().

DateAdd("d", -21, [Forms]![frmDDAI_SB]![txtStartDate])

That may implicitly convert the date field to a date anyway. Not sure you want = also. You mention <= in question.

You are most welcome! Note my comment was in support of Patrick's regarding CDate(). If that is what solved the issue, then please know you won't offend me any by requesting a Moderator change this to a split or credit to Patrick. If the DateAdd() is what did it, then glad that helped!

Best regards and happy coding,

Kevin
