Passing Textbox value to Crystal Report Parameter

Hello everyone. Could someone please help with my problem. I already have the codes for this but I can't seem to combine the two.
Legend: dt1 = Dataset
crpt = Crystal Report File

This is my code for loading the database values into the Crystal Report filtered with the value of the txtGender textbox:

C#

SqlConnection conn = conString.getCon();
ReportDocument cy = new ReportDocument();
dt1 ds = new dt1();
conn.Open();
cy.Load(Application.StartupPath + @"\crpt.rpt");



SqlDataAdapter da = new SqlDataAdapter("exec viewInfo @gen", conn);
da.SelectCommand.Parameters.AddWithValue("@gen", txtGender.Text);


da.Fill(ds.Info);
cy.SetDataSource(ds);

crystalReportViewer1.ReportSource = cy;

conn.Close();

While this is my code for Passing the textbox txtGender value into the Crystal Report Parameter object named "Gen":

C#

ParameterFields pField = new ParameterFields();
ParameterField pTitle = new ParameterField();
ParameterDiscreteValue pValue = new ParameterDiscreteValue();

pTitle.ParameterFieldName = "Gen"; //the name of the field @ Crystal Report

pValue.Value = txtGender.Text; //sending the text box value
pTitle.CurrentValues.Add(pValue);
pField.Add(pTitle);

crystalReportViewer1.ParameterFieldInfo = pField;


crpt objBT = new crpt();
objBT.Refresh();

crystalReportViewer1.ReportSource = objBT;

My problem is how do I combine these two codes so that when I enter the value in the textbox it will load the database values into the Crystal Report and pass the value of the textbox into the Crystal Report Parameter Object "Gen". I have tried combining these codes but it prompts a message "Parameter value is incorrect". Anyone?
