      now i need to calculate the 2 yr avergae for a selected week

       

      count(disctinct (year) =3  but i need 2 here if i subtact the vaule using -1 then if user selects single year whole vaule is 0

       

      how to write a expression for this ?

       

      i need a expression some what like this

       

      (sum( max( week) + sum( max(week-52))/count(max(week) + count(max(week-52))

       

      here (week-52) is the previous week but count(max(week) is showing null
