Hi Charles:

Thanks a lot for your reply and a description about lists and bookmarks. Unfortunately, the organization I work for is too big and it won't be possible to train each and everyone.

However, since, it looks like we don't have any other option, we will just put a comment in the document (it's a pity, I wish Microsoft could have been more innovative), so that the user know that they have to update the code before they update the TOC.

I hope it works. Meanwhile, if you find something else, please let me know.

Thanks.
