Word document page sub-totals

I am trying to help a friend set up a fairly complicated document (an antiques appraisal). It has 6 initial pages with mostly boiler plate text, but with things like first name and last name. It also has a table of properties starting on page 7 which may go on to many pages where each row contains item#, description and amount. The total of the amounts from all pages of the table must be printed on the last page, whatever it turns out to be; the total also needs to appear on page 2. Lastly, she needs a sub-total on each page from page 7 - ??, excluding the last page, of the amounts that appear on that page.

I have accomplished all the requirements except the page sub-totals. Does anyone know how to set up these totals?
