  XPathDocument is optimized for fast, read-only access to your XML document. Try changing to XmlDocument, which allows read/write access, and you should be fine.

  Let me try to explain. The underlying document object model (DOM) can be XPathDocument or XmlDocument (or a few others like XmlDataDocument). Each is optimized for a different scenario. XPathDocument is like a read-only, forward-only cursor in a database. You can call update methods using the cursor, but they will fail because the cursor isn't writable. You can also open an updatable cursor like a keyset cursor. You use the same methods and you will successfully update the data. Does this make more sense

  It's as simple as using XmlDocument where you had XPathDocument.
  
  ' Load the document.
  Dim Doc As New XmlDocument("Data.xml")
  ' Navigate the document with an XPathNavigator.
  Dim Navigator As XPathNavigator = Doc.CreateNavigator()
  ' Move to the root <Debts> element.
  Navigator.MoveToRoot()
  ' Move to the first contained <User > element.
  Navigator.MoveToFirstChild()
  ' Write a new Child
  Dim Writer As XmlWriter = Navigator.AppendChild() ' ERROR HERE!!!!!!
  ' And insert the tag
  navigator.AppendChild.WriteStartElement("User" + NoOfDebtRecs.ToString())
  ' And the data
  Writer.WriteElementString("Name", TextReturned.ToString())
  ' Clear the text box for next time
  AddUser.TextBoxUserName.Text = ""

  I dont think your quite right since
  
  "The < XML:NAMESPACE PREFIX = MSHelp NS = "http://msdn.microsoft.com/mshelp" />XPathNavigator class provides a set of methods used to insert sibling, child and attribute nodes in an XML document. In order to use these methods, the XPathNavigator object must be editable, that is, its CanEdit property must be true."
  
  
  
  Thanks

  XPathNavigator does provide insertion provided that you run it against a DOM that is read/writable, which XPathDocument is not.
