Help finding last piece of puzzle so I can generate a PDF from InfoPath

I'm using Microsoft InfoPath, bundled with Microsoft Office Professional Plus 2010. I created a web browser form (*.xsn). Using the Visual Studio Tools for Applications (VSTA) feature in InfoPath, I added C# managed code behind a button; this button is supposed to create a PDF document using the iTextSharp Dll. Every part of my program "finally" works; however, InfoPath does not recognize references to "Response". My program only works with responses to "Response" commented out. Can anyone tell me what class/DLL I must add to my project in order for my form to compile properly with the "Response" references? The code containing the references to "Response" is listed below:

private void GeneratePDF()
        {
            // Retrieve XML of InfoPath form
            XPathNavigator root = this.MainDataSource.CreateNavigator();
            string xml = root.SelectSingleNode("/my:myFields", this.NamespaceManager).OuterXml;

            // Load XML of InfoPath form into an XmlDocument object
            XmlDocument xmlForm = new XmlDocument();
            xmlForm.LoadXml(xml);

            // Add the 'my' namespace of the form to an XmlNamespaceManager object
            XmlNamespaceManager xmlNameSpaceMgr =
                            new XmlNamespaceManager(
                            new NameTable());
            xmlNameSpaceMgr.AddNamespace("my", "http://schemas.microsoft.com/office/infopath/2003/myXSD/2007-10-02T08:59:49");

            // Retrieve the values of the InfoPath form fields using XPath
            String agency = MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:name_of_agency", NamespaceManager).Value;
            String period = MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:for_the_period", NamespaceManager).Value;
            String org_unit = MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:organization_unit", NamespaceManager).Value;

            // Using iTextSharp to construct a PDF document
            // Create a document-object
            Document document = new Document(PageSize.A4);

            // Create a writer that listens to the document
            // and directs a XML-stream to a MemoryStream
            using (MemoryStream ms = new MemoryStream())
            {
                PdfWriter.GetInstance(document, ms);

                document.Open();

                Font defaultFont = FontFactory.GetFont(
                    FontFactory.HELVETICA, 10, Font.NORMAL);
                Font labelFont = FontFactory.GetFont(
                    FontFactory.HELVETICA, 10, Font.BOLD);

                // Add agency
                Paragraph paragraph = new Paragraph(15F);
                paragraph.Add(new Chunk("Name of Agency: ", labelFont));
                paragraph.Add(new Chunk(agency, defaultFont));
                document.Add(paragraph);

                // Add period
                paragraph = new Paragraph(15F);
                paragraph.Add(new Chunk("For the Period: ", labelFont));
                paragraph.Add(new Chunk(period, defaultFont));
                document.Add(paragraph);

                // Add org_unit
                paragraph = new Paragraph(15F);
                paragraph.Add(new Chunk("Organization Unit: ", labelFont));
                paragraph.Add(new Chunk(org_unit, defaultFont));
                document.Add(paragraph);

                document.Close();

                // Return the InfoPath form as a PDF document
                byte[] data = ms.ToArray();

                //Response.Clear();
                //Response.ClearHeaders();
                //Response.ClearContent();
                //Response.Buffer = true;
                //Response.ContentType = "application/pdf";
                //Response.BinaryWrite(data);
                //Response.End();

                ms.Close();
            }
        }

        public void CTRL53_5_Clicked(object sender, ClickedEventArgs e)
        {
            GeneratePDF();
        }

The DLL's currently linked to my form are listed below:

using Microsoft.Office.InfoPath;
using System;
using System.Xml;
using System.Xml.XPath;
using System.Text;
using System.IO;
using System.Security.Cryptography;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Diagnostics;
using iTextSharp.text;
using iTextSharp.text.pdf;

Thanks in advance for your help.
