((D7*E7)+(G7*H7)+(J7*K7)+(M7*N7)+(P7*Q7)+(S7*T7)+( V7*W7))/(D7+G7+J7+M7+P7+S7+V7))

I have a problem, I'm trying to run the following formula
(=((D7*E7)+(G7*H7)+(J7*K7)+(M7*N7)+(P7*Q7)+(S7*T7) +(V7*W7))/(D7+G7+J7+M7+P7+S7+V7))
which is to find out the average of a weekly call survey but some cells
are
blank due to the fact that there are no value inputed because no calls
where
made on specific day and the end result turns up an error (#DIV/O!). How
can
I make it so if the cells are blank, the end result will turn to display
zero?
