Why am I getting this error with FormatDateTime?

Hi Experts,

I have the following error:

Error Type:
Microsoft JET Database Engine (0x80040E14)
Undefined function 'FormatDateTime' in expression.
/intermodal/load_record/SearchQueries.asp, line 307

line 307 is: rs.Open strSQL,conn

This is my query:

SELECT Load.LoadID, Load.SAPDate, Load.DeliveryNo, Load.ShipmentNo, Load.ManualNote, ShipFrom.ShipFrom, Load.FromProv, ShipTo.ShipTo, Load.ToProv, Load.PayorOfFreight, Transporter.TransName, [ContainerInitial] & ' ' & [ContainerID] AS [Container], Load.Notes, Users.UserID, Format([CreatedOn],'dd/mm/yy') AS CreatedOnDate, Load.UpdatedBy, Load.UpdatedOn, [Container Initials].ContainerInitial, Load.ContainerID FROM (((Users INNER JOIN (Transporter RIGHT JOIN Load ON Transporter.TransID = Load.TransporterUsed) ON Users.User_Key = Load.CreatedBy) LEFT JOIN ShipFrom ON Load.ShipFromID = ShipFrom.ShipFromID) LEFT JOIN ShipTo ON Load.ShipToID = ShipTo.ShipToID) LEFT JOIN [Container Initials] ON Load.ContainerInitialID = [Container Initials].ContainerInitialID WHERE FormatDateTime([CreatedOn],2) Between #05/01/2006# And #05/31/2006# AND ShipFrom.ShipFrom='CA1D' ORDER BY Load.SAPDate DESC;

Thanks
