Crystal Reports Load Report Failed when Applying Current Values

Message

Below is a copy of my code.  I am receiving a Load Report Failed at crReport.DataDefinition.ParameterFields[0].ApplyCurrentValues(values0);

Any ideas?

CrystalDecisions.Shared.ParameterDiscreteValue pdv = new CrystalDecisions.Shared.ParameterDiscreteValue();

CrystalDecisions.CrystalReports.Engine.ReportDocument crReport = new CrystalDecisions.CrystalReports.Engine.ReportDocument();

crReport.FileName = "Report1.rpt"; ;

crReport.Load(@"C:\Apps\Web\TestCFML\" + crReport.FileName, OpenReportMethod.OpenReportByDefault);

//this.CrystalReportViewer1.ReportSource = Server.MapPath("report1.rpt");

this.CrystalReportViewer1.ReportSource = @"C:\Apps\Web\TestCFML\" + crReport.FileName;

ParameterValues values0 = new ParameterValues();

pdv.Value = "MIA";

values0.Add(pdv);
crReport.DataDefinition.ParameterFields[0].ApplyCurrentValues(values0);
ParameterValues values1 = new ParameterValues();

pdv.Value = DateTime.Now.AddDays(-6);

values1.Add(pdv);
crReport.DataDefinition.ParameterFields[1].ApplyCurrentValues(values1);
ParameterValues values2 = new ParameterValues();

pdv.Value = DateTime.Now;

values2.Add(pdv);
crReport.DataDefinition.ParameterFields[2].ApplyCurrentValues(values2);
ParameterValues values3 = new ParameterValues();

pdv.Value = "TEST";

values3.Add(pdv);
crReport.DataDefinition.ParameterFields[3].ApplyCurrentValues(values3);
