Default Chapter 15 Problem

Ok...here's another one I followed to the letter and syntax errors all over the place.

First, Page 397 TIO-1503, step one there should be a "/" before the "bookstore/genre[@name='Fiction']/book

This happens in several places.

Also--

WHY when I follow TIO 1503 do I not get a root "Bookstore" node...this is what i Get:
(NOTE--I had to manually add the datamember "Bookstore"..it didn't appear in the databindings list)

 A Tale of Two Cities

  Abstract...
  Abstract...
  Abstract...

 Pride And Prejudice

  Abstract...
  Abstract...
  Abstract...

 The Old Man and the Sea

  Abstract...
  Abstract...
  Abstract...

And here is my code:

<%@ Page Language="VB" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">

</script>

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Untitled Page</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:XmlDataSource ID="XmlDataSource1" runat="server" DataFile="../App_Data/Bookstore.xml"
            XPath="/Bookstore/genre[@name='Fiction']/*"></asp:XmlDataSource>
        <asp:TreeView ID="TreeView1" runat="server" DataSourceID="XmlDataSource1">
            <DataBindings>
                <asp:TreeNodeBinding DataMember="Bookstore" TextField="#Name" />
                <asp:TreeNodeBinding DataMember="genre" TextField="name" />
                <asp:TreeNodeBinding DataMember="book" TextField="Title" />
                <asp:TreeNodeBinding DataMember="chapter" TextField="#InnerText" />
            </DataBindings>
        </asp:TreeView>

    </div>
    </form>
