Thank you for your reply. But this one seems not work. One of my concern is actually when multiple dates are selected. For example, when Year=2014, Month=01, Day=01,02,03,04,05, can I use makedate to display 01/01/2014,01/02/2014,01/03/2014, 01/04/2014,01/05/2014? If MakeDate does work, can I use OrderDate=Makedate(Year-1, num(Month), Day) to get the data when OrderDate=01/01/2013,01/02/2013,01/03/2013,01/04/2013, 01/05/2013?
