title: SSRS grouping on fields = a multi value parameter
body: <p>I have a SSRS Report where one of the parameters is a multi-select. I need a row group with a aggregate row that has a totals row that sums some number based on ONLY what the user selects from the drop down. For instance....if the drop down contains A = 4, B = 7, C = 1 and D = 3, let's say the user selects A and C only. The grouping only show rows containing A and C (not separating them out into groups, just returning rows ) and the total should = 5. </p>
