I had a dateset within SSRS 2005 as shown below, which uses a @StartDate and @EndDate parameter for the report to work, Within the Report properties the @StartData and @EndDate both uses data type of DateTime. SELECT * FROM dbo.MyTable where Date between @Startdate and @endDate I can run the report with SSRS 2005 which allows me to select the data parameters and run the report. but when i deploy the report. i get the following error message, The 'Startdate' parameter is missing a value why is this occuring?
