ASP.NET C# Hyperlink passing values back to parent form

Hi there...

Been pulling my hair out over this and I am obviously missing something simple and need another pair of eyes... so please help... :-)

I have a simple form that looks like this:

<%@ Page Language="C#" ContentType="text/html" ResponseEncoding="iso-8859-1" %>
<script runat="server">
protected void Page_Load(Object Src, EventArgs E)
{
      btnAddressFinder.Attributes.Add("onclick", "window.open('address-finder.aspx? txtAddressFinder=test','popup','width=250,height=250,left=270,top=180');");

}
</script>
<html>
<title></title>
</head>
<form id="Form1" method="post" runat="server">

<table width="742">
      <tr>
            <td width="20"> </td>
<td>
<h1>Postal Address</h1>
<table width="100%" border="0">
<tr>
<td width="30%"><p><strong>Title</strong></p></td>
<td width="70%"><asp:dropdownlist AutoPostBack="false" ID="ddTitle" runat="server"></asp:dropdownlist></td>
</tr>
<tr>
<td width="30%"><p><strong>First name</strong></p></td>
<td width="70%"><asp:textbox ID="txtFirstName" runat="server" TextMode="SingleLine" /></td>
</tr>
<tr>
<td width="30%"><p><strong>Surname</strong></p></td>
<td width="70%"><asp:textbox ID="txtSurname" runat="server" TextMode="SingleLine" /></td>
</tr>
<tr>
<td colspan="2"> </td>
</tr>
<tr>
<td colspan="2"><p><strong>Please enter your postcode in the textbox
below and click "Address Finder" to let us complete
your address details for you.</strong></p></td>
</tr>
<tr>
<td> </td>
<td> </td>
</tr>
<tr>
<td width="30%"> </td>
<td width="70%">
<asp:textbox ID="txtAddressFinder" runat="server" TextMode="SingleLine" />
<asp:button ID="btnAddressFinder" Text="Address Finder" runat="server"/></td>
</tr>
</table>
</form>
</body>
</html>

The address finder popup is working fine... and the address finder popup looks like this:

<%@ Page Language="C#" ContentType="text/html" ResponseEncoding="iso-8859-1" %>
<script runat="server">
protected void Page_Load(Object Src, EventArgs E)
{

      HyperLink1.NavigateUrl = "javascript:;";
      HyperLink1.Attributes.Add("onclick", "window.opener.document.forms(0).txtAddressFinder.value='2222';self.close()");

}
</script>
<html>
<head>
<title>Postal Address Finder</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<body>
<form runat="server">
      <asp:hyperlink runat="server" ID="HyperLink1" ToolTip="Hyperlink">Hyperlink</asp:hyperlink>
</form>
</body>
</html>

The problem I am having is that when I click on the link nothing happens? If I remove the part of the script to post the value back to the form - and just leave the self.close() - it works fine and the popup closes?

Can anyone see what I am doing wrong here?

Thanks for the help!
