Im Using the function SUM and I think that it's correct, because work in others Text Objects in the same report.

Im Using This expression: [SUM(<dbdRespostas."count">,MasterData4)] -does not work
In Other TextObject (Same "Line") I Use: [dbdRespostas."count"] - works

What surprises me is that in the GroupFooter i have [SUM(<dbdRespostas."count">,MasterData4)]

and it wors fine too!

What Can be wrong?

Thanks

    So... How I can take a sum of the values in the row?

    I need of a accumulate colum like this


    Option | Value | Accumulated

    option1 | 2 | (2)
    option2 | 5 | (7)
    option3 | 3 | (10)

    How I can do this?

    Thanks

    use a typed variable in the accumulated memo [acc]
    At the top of code page create a typed variable acc: extended;
    initialize it to 0 in the begin end.block at the bottom of the code page
    or in an obp event of a band or header.
    in the obp event of the memo write code to accumulate the value of the value field
    acc:= acc +<datasetname.fieldname>;
