XML Experts, pls Help...

I'm having some trouble with XML. In my application, I have a combo box populated with all of the Presentation_Name element's text added to the combo box. Now, when I select a presentation name from the combo box, another combobox right below the first one, gets populated with all of the messages that fall under the Presentation_Name. For Example, if I select Return Policy from the combo box, the combo box below it gets populated with only one message, "CC Regarding return policy"

This is what I got so far:
Thank You

Option Explicit
Dim xmlNote As New DOMDocument
Dim xmlNode As IXMLDOMNode
 
Private Sub PopulateAddNotes()
    '// Load XML into DOM Object
    xmlNote.Load "C:\Notes.xml"
    
    '// Populate combo box with all presentation names
    For Each xmlNode In xmlNote.documentElement.selectNodes("//PRESENTATION_NAME")
        Combo1.AddItem xmlNode.Text
    Next
End Sub

Private Sub Combo1_Click()
    Dim strNoteType As String
    Dim xmlNodeList As IXMLDOMNodeList
        
    strNoteType = Combo1.Text
    Set xmlNodeList = xmlNote.documentElement.selectNodes("//PRESENTATION_NAME")
        
    For Each xmlNode In xmlNodeList
        If xmlNode.Text = strNoteType Then
            Combo2.AddItem xmlNode.parentNode.selectSingleNode("MESSAGES/MESSAGE/COMBO_NAME").Text
            Text1.Text = xmlNode.parentNode.selectSingleNode("MESSAGES/MESSAGE/TEXT_NAME").Text
        End If
    Next
End Sub
