Passing a Parameter to a Crystal Rep

Greetings Babu,
I am using a dataset that consists of a SQL Server Stored procedure with a parameter, I would like to have a bottun on a windows form in my C# app that the user would press to pass in a param, do you know how I can pass in a param to my crystal report? EVerytime I add a param, and run my app, this dialog box pops up and asks for the parameter, i don't want this to happen because I want my text field to take care of passing hte param in? Could you provide any advice?

Thanks!!!
