    How to calculate the difference between two fields of different lines in automatic

    patrice GARCIA

      Hello

      I load into a table daily records matching counters printers. These counters represent the total number of pages printed. I would calculate the number of printed pages per day to display the graph of the number of printed pages per month.

      How I can do ?

      Thank you for your help
