    How do I apply a cumulative sum to a series of data containing monthly sales?



      If I have data organised in two columns:



      ([sales value])   the data in this column is simply the sales volume for the month in the adjacent column


      And I want to display the monthly sales as a cumulative result, what is the simplest expression to use?




      Month          Sales value


      Jan               £200

      Feb               £190

      March           £75

      April               £140

      May               £50
