switch back from the second document which is loaded last back to the
main.,

Private Sub cmdOK_Click()
   'If the OK button is clicked

doc2 = Documents.Add("C:\OFFICE\WORD\TEMPLATES\bill3.dot")

With ActiveDocument
Selection.WholeStory
Selection.PasteAndFormat (wdPasteDefault)
Selection.HomeKey Unit:=wdStory
   'Goes into the header
ActiveWindow.ActivePane.View.SeekView = wdSeekCurrentPageHeader
   'Inserts the AutoText
Selection.TypeText Text:="NotVAT"
Selection.Range.InsertAutoText
   'Goes back into the body of the document
ActiveWindow.ActivePane.View.SeekView = wdSeekMainDocument

End With
