Date criteria in a query

[Humpty]

Wonder if anyone can help with the syntax in this query? It always returns no results and I can't for the life of me understand why.

SELECT tblExpectedShipments.ShipmentDate
FROM tblExpectedShipments
WHERE (((tblExpectedShipments.ShipmentDate)=IIf([Forms]![frmSelectShipperReport]![chkOverdue]=0,(tblExpectedShipments.ShipmentDate)>Date(),(tblExpectedShipments.ShipmentDate)<Date())));

Any pointers would be greatly appreciated. Thanks.

not entirely sure, but perhaps

SELECT tblExpectedShipments.ShipmentDate
FROM tblExpectedShipments
WHERE (((tblExpectedShipments.ShipmentDate)=#IIf([Forms]![frmSelectShipperReport]![chkOverdue]=0,(tblExpectedShipments.ShipmentDate)>Date(),(tblExpectedShipments.ShipmentDate)<Date())#));

Basically wrapping the result of the Iif with ## so that it is forced to be seen as a date value.

Thanks workmad. It looked like it could be a possible solution but afraid it just returns the error "The expression you entered has and invalid date value". Any other thoughts?

Hmm... of course it wouldn't. Should really check queries before changing them

tblExpectedShipments.ShipmentDate>Date() is a true/false boolean expression.

if you are comparing this to a date, then no you wouldn't ever get any results
