Hello. I have a web page that uses Crystal Reports. When the user logs on and clicks on the Print Blank Report button the report page comes up but no report is in the Report Viewer. When I test out other things on the same page, those objects show up but not the Blank report that was made. I have tried to recreate the report and the web page that displays the report over again but the same thing happens. What did I do wrong or forgot?

Here is the Web Page code:

ASP.NET

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="FINBlankA.aspx.cs" Inherits="FINAPP.FINBlankA" %>

<%@ Register assembly="CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" namespace="CrystalDecisions.Web" tagprefix="CR" %>

            ToolbarImagesFolderUrl="" ToolPanelView="None" ToolPanelWidth="200px" 
            Width="903px" />
        <CR:CrystalReportSource ID="CrystalReportSourceA"  runat="server">
            <Report FileName="BlankWorkSheetA.rpt">
            </Report>
        </CR:CrystalReportSource>
        <asp:TextBox ID="TextBoxUser_ID" runat="server" Visible="False"></asp:TextBox>
    
    </div>
    </form>
</body>
</html>

            paramDiscreteValue.Value = TextBoxUser_ID.Text;
            paramFields.Add(paramField);
            CrystalReportViewer1.ParameterFieldInfo = paramFields;

            CrystalReportViewer1.ReportSource = CrystalReport;
            con.Close();
        }
