I am using nested IncludeText fields to merge documents
in Word 2002.
The structure is like this:
A.DOC:
 includetext B.DOC
B.DOC
 includetext C.DOC
 includetext D.DOC

This is working great, except for one thing.  For all
merges, the Heading styles are outline-numbered, and in
one case with docs A,B,C,& D, the contents of C & D
appear in A with all styles and numbering adjusted
perfectly (C's numbering is a continuation of A's, and
D's from A & C's etc), but in another case with docs
A1,B1,C1, & D1, they appear perfectly EXCEPT numbering
has been set to None.  A1's numbering is fine both before
& after the includetext of B1, but C1 & D1's numbering is
OFF. However, C1 & D1 styles are all OK.  It looks good,
just no numbering.

We have tried hard to use exactly the same available
styles and use only standard styles in all documents.  

Finally, in all cases, the contents of B looks fine
before it is included into A - the styles and numbering
are as they should be, adjusted correctly (the heading
numbering from D is continued from C).

Any clue as to what is going on here?

Thanks,
Ian
