How can I use In operator in the SQL report builder for one of the column.... I want to have field expression like this =IIf(Fields!Abdomenor_Groin.Value In Parameters!BodyChart.Value(), Fields!Combine_Injured_Body_Chart.Value, 0)...but it is syntax error. How do I achieve this.

 Have you tried something like the approach in this Stack Overflow question? http://stackoverflow.com/questions/7363027/how-to-check-if-a-value-is-selected-in-a-multi-value-parameter
