Problem Displaying Crystal Parameter on Report

[mjjks]

Hi All,
I created stand alone Crystal report using version XI.
It has an input parameter for data source (stored procedure). Parameter shows on report if I run report by itself, but not when I run from application (C# - Windows app, VS2005,.NET 2.0). Report data changes as parameter changes, but doesn't display parameter.

Code I'm using is below. Anything am I doing wrong here?

Thanks in advance.

private void ShowMarkersApart(int iParam)
        {
            SqlDataAdapter da = new SqlDataAdapter();
            da.SelectCommand = new SqlCommand("exec usp_MRKR_RPT " + iParam, this.GetConnection("HWYDB"));
            DataTable dt = new DataTable("MRKR");
            da.Fill(dt);
            
            Markers_Miles_Apart oRpt = new 
            Markers_Miles_Apart(); [COLOR=green]//embedded crystal report[/color green]
            oRpt.SetParameterValue("@MileTolerance",iParam);
            oRpt.SetDataSource(dt.DefaultView);
            crw.ReportSource = oRpt; [COLOR=green]// crystal viewer[/color green]

        }
