Hi.

I want to make cells of a columm, sum the cell in top of
itself. (im in c13... =sum (c12) and so on..)

when i insert a row (wich i have to) the cell doesn´t sum
the previous (on top) cell, it sum 2 cells up. and when i
delete that row it gives me #ref.

How can i do this!! i have to make SUM based on the
value of the cells in that row. (Sumif)

Thanks!
