System.Net.Mail Large HTML message

I have a small survey application that I put together within an ASP.NET CMS (sitefinity).  The logic of the survey is to store the SelectedItems from the various button list controls in hidden fields (upon button clicks).  As each question is answered a new panel of questions is made visible and the answered questions are hidden.

Upon completion the final event is to email the SelectedItems along with a large HTML message to the user.  The SelectedValues are placed in various locations of the HTML message.  A mail merge if you will.

Here is my problem: I can only get the SelectedItems into the HTML message under certain limited conditions.

1.  Using a Token Replacement scheme allows me to "Tokenize" the fields within a static ASPX page.  However, the tokens can't be linked to the server controls (the hidden fields) inside of the user control .ascx file.  
Here is an example of my code for this situation.
.ascx

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="NeedsSurvey.ascx.cs" Inherits="NeedsSurvey_NeedsSurvey" ClassName="NeedSurvey" %> <asp:Panel runat="server" ID="panel1">     1. Which of the following best describes the personal needs you feel are the most     immediate?     <br />     <br />     <asp:RadioButtonList ID="RadioButtonList1" runat="server">         <asp:ListItem>Help with everday expenses</asp:ListItem>         <asp:ListItem>Paying off debt</asp:ListItem>         <asp:ListItem>Taking a vacation</asp:ListItem>         <asp:ListItem>Home improvments</asp:ListItem>         <asp:ListItem>Better medical coverage</asp:ListItem>     </asp:RadioButtonList>     <asp:Button ID="Button1" runat="server" Text="Button" OnClick="btn_Click1" />     <asp:Label ID="Label1" runat="server"></asp:Label>     <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="RadioButtonList1"         ErrorMessage="Please select an answer"></asp:RequiredFieldValidator> </asp:Panel>

Here is the code behind
.ascs.cs

using System; using System.Data; using System.Configuration; using System.Collections; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using System.Net.Mail; using System.Net; using System.IO; public partial class NeedsSurvey_NeedsSurvey : System.Web.UI.UserControl {         #region EventHandlers     protected void btn_Click1(object sender, EventArgs e)     {         try         {             panel1.Visible = false;             panel2.Visible = true;         }         catch (Exception ex)         {             Label1.Text = ex.Message;         }       q1.Value = RadioButtonList1.SelectedItem.Text;                } #endregion     public void Confirm_Send(object sender, EventArgs e)     {         //create the mail message         MailMessage mail = new MailMessage();         //set the addresses         mail.From = new MailAddress("xxx.com");         mail.To.Add("xxx.com");         //set the content         mail.Subject = "Website Lead";         string html = ScreenScrapeHtml("http://localhost/demo/mycontrols/needssurvey.aspx");         mail.Body = html;         mail.IsBodyHtml = true;         //send the message         SmtpClient smtp = new SmtpClient("xxx.com");         smtp.Credentials = new System.Net.NetworkCredential("xxx", "xxx");         smtp.Send(mail);     }     public string ScreenScrapeHtml(string url)     {         WebRequest objRequest = System.Net.HttpWebRequest.Create(url);         StreamReader sr = new StreamReader(objRequest.GetResponse().GetResponseStream());         string result = sr.ReadToEnd();         sr.Close();         return result;     }     }

The ASPX page is just an HTML formatted message that looks like, "Dear [$FirstName$], etc" with a code behind file for Tokenizing. The code for this was written by Damon Armstrong and can be found Here. I used the code exactly as written.  Again, the problem is I can't get my hidden fields to link to the external ASPX page nor can I tokenize them.

2.  The other method is to place the html message in the User Control within a Literal control and call the control at the SEND email event.  Unfortunately you can not place server controls within a Literal control to call the values of the hidden fields, nor is it possible to use a
