I am working on designing a protected template. I have set Editing
Restrictions to "No changes (Read only)". Under Exceptions, I have selected
areas of the document that I want everyone to be able to edit--one area being
the table of contents. I then protect the document. The problem occurs when
a user builds a document using the template. They can only update the table
of contents once. If an attempt is made to update the table of contents
twice, the user will find that Update Field is unavailable (disabled). Is
there a way to prevent this from happening so that the user can update the
table of contents whenever they need to?

Thanks
