Here is a very quick example of a MM baced on an existing MM template document.
VB Code:
  1. Option Explicit
  2. 'Add reference to MS Word xx.0 Object Library
  3. Private moApp As Word.Application
  4.  
  5. Private Sub Command1_Click()
  6.     Dim oDoc As Word.Document
  7.     moApp.Visible = True
  8.     Set oDoc = moApp.Documents.Add("D:\Test.dot", , , True)
  9.     With oDoc.MailMerge
  10.         .MainDocumentType = wdFormLetters
  11.         .OpenDataSource Name:="D:\RobDog888.mdb", LinkToSource:=True, Connection:="TABLE ClientData"
  12.     End With
  13.     With oDoc.MailMerge.DataSource
  14.         .FirstRecord = 1
  15.         .LastRecord = 20
  16.     End With
  17.     With oDoc.MailMerge
  18.         .Destination = wdSendToPrinter 'wdSendToNewDocument; wdSendToFax; wdSendToEmail
  19.         .Execute True
  20.     End With
  21.  
  22. End Sub
  23.  
  24. Private Sub Form_Load()
  25.     Set moApp = New Word.Application
  26. End Sub
