I have several rows with the same formula but they are seperated, in some
cases, by rows with other information to prevent me from just dragging a
formula down to other rows.

Ex. While in row 13: B13*C13+B13*D13+B13*E13
While in row 20: B20*C20+....

how can I write a formula to populate the "13" or "20" automatically for
whatever row I am in?

Thanks,
Dave
