I am controling this through Visual Basic 6.

Thanks.

The following is a recording of the action of formatting the page numbers to
include the chapter number that can be done via Insert>Page Numbers>Format.

    With Selection.Sections(1).Headers(1).PageNumbers
        .NumberStyle = wdPageNumberStyleArabic
        .IncludeChapterNumber = True
        .HeadingLevelForChapter = 0
        .ChapterPageSeparator = wdSeparatorHyphen
        .RestartNumberingAtSection = True
        .StartingNumber = 1
    End With

You may have to tweak it for your purposes.

Please post any follow-up or new questions to the Newsgroups so that others
may benefit therefrom or contribute thereto.

Hope this helps,
