Linking two "total" pages to create a "Complete Total" page
 

I have two workbooks that I have compiled into one. Each workbook has
formulas from previous pages creating a "total" page that formulates on its
own. For example - there are 10 retail store specific totals that link to a
total page for all ten stores, and then another 10 stores with the same total
page for those corresponding ten stores. Now I need a page that links each of
these " total" pages into one complete total page at the end. Does anyone
know how to link these two pages? The orginal formulas were in place when I
took over the workbooks, so I have no idea how they were done.

Thanks in advance for any help.
