You cannot select the MathStatistics object in a SummaryCell.Calculation property if you have placed a SummaryCell in a row in the designer. The MathStatistics option is available only when SummaryCell is placed in the ColumnHeaderSection or ColumnFooterSection. When working in a row, you can use the Expression object to get the sum of cell values.
