Thanks for the suggestion, but in SQL 2008 Express version Business Intelligence Development Studio (Visual Studio by any other name!@#$), its a new user interface

There is a "Report Data" tab that sits on the left hand side of the screen which has "built in fields", "parameters" and "datasets" as separate tree nodes. I cant find any up/down arrows in the parameter tree to re-order.

Anyone else using Vis Studio 2008 that can tell me how to re-order parameters????
