In the "start of Option Filter & Order" embed point of an application I have
     IF p_web.getSessionLevel() <= 4 !Dealers
          WOR:OrderStatusID_OptionView{prop:filter} = p_web.CleanFilter(WOR:OrderStatusID_OptionView,'WOS:DisplayOrder <= 2 ') 
      END
Which works fine. It only displays the WOS:DisplayOrder = 1 and     WOS:DisplayOrder = 2 records.
I now want to also display WOS:DisplayOrder = 5
I tried
     IF p_web.getSessionLevel() <= 4 !Dealers
          WOR:OrderStatusID_OptionView{prop:filter} = p_web.CleanFilter(WOR:OrderStatusID_OptionView,'WOS:DisplayOrder <= 2 AND WOS:DisplayOrder = 5 ') 
      END
but nothing is displayed in the drop down.
What is the correct command?
