SSRS report, I have a parameter that accepts integer values and (to make it optional) I have the "Allow null value" box checked. That's fine. What isn't fine is that there are NO default values assigned to this parameter, but when I run the report the "null" box IS checked and the report runs automatically. I want the null box to start out UNchecked and for the user to either fill in the parameter box OR check the NULL box before the report runs. Is there something I'm missing here? Why is this parameter pulling in null as the default, and is there a way for me to stop it?
