I have an ASP .NET 3.5 [C#] application that is using crystal reports. I want to, if possible, design a report (which i've already done), and in the designer add a dynamic parameter field that prompts the user for a value (preferably from a drop down list of valid values) and have it actually work. Currently when I add the parameter field in the designer, save it and then go out to the web page a couple things are happening. 1st, my list (data set) isn't filtered to only the values that meet / match the parameter. 2nd, when i attempt to click into or change the parameter value off to the left upper corner I get an error messag similar to: "Object not set to a value". How do I get this to work as I need it to?
