    sum of the last of 3 selected months

      hi

      i got the following problem:

       

      i want to sum only the last month even if 3 or more months are in a listbox  selected.

       

      at the moment  the expression looks like this:

       

       

      sum ( {  $ < TypeOfVoucher = { 'Sale' } , MonthNum = {  '9' '} >} Amount  )

       

       

       

       

      I would be thankful for any advice.

       

      greetings

      daniel
