Business expenses do not add correctly when totaled on business summary - off by over $7000

[vikingcat]

I cannot get the business summary sheet to even come close to the expenses entered on the "some common business expenses" sheet. That sheet does sum the detail inputs by category (e.g. communication) correctly onto the common expenses sheet. But the sum of those expenses does not transfer correctly onto the business summary sheet. It is off by over $7000. 

HOW do I solve this apparent screw-up?
