Hi Chuck-
You're on the right track, as Protect Sheet is what you need to use for the
protection of its content. The hierarchical issue is not really valid, as
you _do not_ need to use Protect Workbook in order to protect any given
sheet(s), nor do you have to protect any sheets in a protected workbook.
Workbook protection prevents a user from adding or deleting sheets,
rearranging sheets in a book, and other more global aspects of the workbook,
itself. And you are correct, it _does not_ prevent changes to any
unprotected sheets, although it does prevent the sheet from being deleted
from the workbook.
