Hi, Im looking to setup a multiple value parameter based report. I found some instructions which demonstrate how to do this by using the In function within your query FROM [Report] WHERE [Report].order_no IN (@SalesOrderNumber) Setting up your Parameter as a multi value parameter and adding =split(Parameters!SalesOrderNumber.Value, ",") into the Dataset Parameter Properties. If I do this it errors with The Value expression for the query parameter ‘@SalesOrderNumber’ contains an error: Conversion from type 'Object()' to type 'String' is not valid. Any ideas how to overcome this? Thanks as always
