Word 2007 and Forms Mail Merge Problem

Is anyone else having problems with mail merge in Word 2007?

I am following Doc ID 297410.1 and my program is hanging after it does a client_ole2.get_obj_property(word_app,'ActiveDocument'); 

The next line is

 Client_ole2.get_obj_property(active,'MailMerge');

and it hangs at that point.

Here is the trigger:

declare
 word_doc Client_OLE2.OBJ_TYPE;
 word_app Client_OLE2.OBJ_TYPE;
 m_obj Client_OLE2.OBJ_TYPE;
 active  Client_OLE2.obj_type;
 word_docs  Client_OLE2.OBJ_TYPE;
 ls_arg_list Client_OLE2.LIST_TYPE;
 v_arg_list  Client_OLE2.LIST_TYPE;
begin
 word_app := Client_OLE2.CREATE_OBJ('Word.Application');
