Yes, and 29/01/2003.
That's, of course (!), why you must change the "w" to "ww":
SELECT
tblBooking.ID,
tblBooking.Interval,
tblBooking.DateStart,
tblBooking.DateEnd,
DateAdd([Interval],[Factor],[DateStart]) AS DateRepeat
FROM
tblBooking,
tbzMultiply
WHERE
(tbzMultiply.Factor <= DateDiff([Interval],[DateStart],[DateEnd]))
AND
(tblBooking.Interval IN ("h","d","ww","m","q"))
ORDER BY
tblBooking.ID,
tbzMultiply.Factor;
Also:
