maintain scrollbar position

In a C# 2010 web form application, I want to maintain the scroll bar position in Panel1 listeb below. According to the following
link: http://gnidesign.blogspot.com/2011/06/how-to-maintain-page-scroll-on-postback.html, the javascript code that I supplied below
should work. My problem is there is not a 'head' html tag for me to embed the javascript code into.

Thus can you tell me what is wrong with the Javascript code I have below? Do I have the code in the wrong postion of the *.aspx
page?
   Can you tell me how to maintain the scrollbar position of panel1?

   Here is the code I am referring to:
<%@ Page Title="" Language="C#" MasterPageFile="~/App.Master" AutoEventWireup="true" MaintainScrollPositionOnPostback="true"
    CodeBehind="Atts.aspx.cs" Inherits="RpcSupport.Atts" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajx" %>








                                            Width="50%">











                                                                    MaxLength="10" />
                                                                    AutoPostBack="true" MaxLength="100" />
                                                                TargetControlID="txtOrgName" ServiceMethod="GetOrgAttList" ServicePath="Atts.aspx"
                                    MinimumPrefixLength="1" CompletionInterval="200" CompletionSetCount="50">







                                                                            CssClass="TextBoxStyle">

runat="server" ControlToValidate="txtOrgName" ErrorMessage="'Organization Name' is a required field." />

2. var IsPostBack= '<%=IsPostBack.ToString() %>';
3. window.onload = function(){

5. if(strCook.indexOf("!~")!=0){
6. var intS = strCook.indexOf("!~");
7. var intE = strCook.indexOf("~!");
8. var strPos = strCook.substring(intS+2,intE);
9. if (IsPostBack=='True')
10. {
11. document.getElementById("<%=pnlTree.ClientID %>").scrollTop = strPos;
12. }
13. else
14. {
15. document.cookie = "yPos=!~0~!";
16. }
17. }

20. var intY = document.getElementById("<%=pnlTree.ClientID %>").scrollTop;
21. document.title = intY;
22. document.cookie = "yPos=!~" + intY + "~!";
