Merge to Publisher from Access

I have a complex mail-merge publisher (.pub) do***ent ( that is linked to a

table in MS Access 2003.  I would like to automate the merge from within 
access, so that when i click a button, the merged publisherdo***ent opens
and 
hopefully completes the merge to another/ final.pub do***ent.  My problem
is 
that when I use the codein trying to get Publisher to open:
    Dim oApp As Object
    Dim strDocPath As String
    
    strDocPath = "C:\\..."
    Set oApp = CreateObject(Publisher.Application)
    oApp.Do***ents.Open (strDocPath)
     oApp.Visible = True

I get an "Object doesn't sup****t this method or property." error.  I
suspect 
this is a reference problem? 
Appreciate any help here. Tx
