Subtracting hours in a work schedule

I believe that this is a misunderstanding.
I want to put the table (AE:AM on sheet "store3") on both sheet, or leave it on store 3 page, but the totals need to reflect both stores input.
When I showed it to her, it did not keep a running total between both store, it only totaled store 3.
I have attached the file as it is so far.
I am talking about the chart in AE:AM.
Sorry for any confusion that I may have caused.
Thanks
