Word Combobox From a Database

Hi all -

I have a word document (Word 2003) which has a combobox.  I'm trying to get the names from my database (Access 2003) to be populated within the drop down list.  The Database resides in my C Drive.
(Full Path; C:\db\Names.mdb)

In the database, I have a table called "tblNames" and within that table, I have a field name called "StaffNames" which its data type is set to "Text".

In my word document, I have entered the following code (Below), and setup the references.
But, the "StaffNames" are not being populated in the word document combobox?

Does anyone know why and perhaps can help me with the coding?  
Thank you.

             "Data Source=C:\db\Names.mdb"
    rst.Open "SELECT DISTINCT [StaffNames] FROM tblNames ORDER BY [StaffNames];", _
             cnn, adOpenStatic
    rst.MoveFirst
    With Me.ComboBox1
        .Clear
        Do
            .AddItem rst![StaffNames]
            rst.MoveNext
        Loop Until rst.EOF
    End With
UserForm_Initialize_Exit:
    On Error Resume Next
    rst.Close
    cnn.Close
    Set rst = Nothing
    Set cnn = Nothing
    Exit Sub
UserForm_Initialize_Err:
    MsgBox Err.Number & vbCrLf & Err.Description, vbCritical, "Error!"
    Resume UserForm_Initialize_Exit
End Sub
