Multi column sumproduct

I think the sumproduct is the correct formula but I can't get this right. I
am trying to get a total amount of parts though multiple issues as shown
below:

Column g h i j k l m
n
pears 3 apples 2 oranges 5 bananas 6
oranges 5 bananas 4 apples 8 pears 10

As you can see, each coulmn will not equal the same item. I need the total
of each item for the whole sheet. The information will be updated monthly so
the totals will change. My goal is to, on another spreadsheet within the
same workbook, have the items in column a and the totals in column b. All
help is much appreciated.
