How to not show the popup window when hit the "Go to Next Page" button on Asp.net page crystal report

Hi,

  There is a crystal report on my asp.net application, When I open this crystal report, it will popup parameter window and I need to select Fiscal year and some version  from the list, then it would generate the report, however, when I want to see second, third, forth page, I click on "Go to next page" button, it would popup another parameter window and require me to select some value again, how can I make this popup window disable (or disappear)  when I hit "Go to nextpage" button and can go to next page of the report directly?

  this is my part of code on asp.net cs page:

        ConnectionInfo connectionInfo = new ConnectionInfo();
        CrystalDecisions.CrystalReports.Engine.ReportDocument boReportDocument;

        string rptFile = ((BaseApplicationPage)(this.Page)).Decrypt(this.Page.Request.QueryString["Name"]);
        boReportDocument = new CrystalDecisions.CrystalReports.Engine.ReportDocument();
        boReportDocument.Load(Server.MapPath("~/Crystal/" + rptFile));
        CrystalReportViewer1.ReportSource = boReportDocument;

        connectionInfo.ServerName = "XXXXX";
        connectionInfo.DatabaseName = "XXXXX";

thanks
