Hi Bill

Just amend Ron's formula to 0 rather than =0 to account for the blank
rows that you say you have after every set of 3 numbers. Adjusting to
start in H2 the formula would be
=IF(G20,0,IF(G1="",H1,N(H1))-G2)
and copied down

Thanks Ron for your input
There's one thing with your formula , it needs to accumulate
all the entries in column "H" from zero to zero .
G H
-5.0 5.0
-5.0 10.0
-5.0 15.0

22.5 0.0 (because of positive figure in column (G)
-7.0 7.0
-7.0 14.0

-5.0 19.0
-5.0 24.0
-5.0 29.0

-7.0 36.0 ....(sum because of negative figures in
12.0 0.0 column (G) from zerro to zerro)
-7.0 7.0
I apologise for not making my last post very clear

thank you
regards bill

Try something like this:

With
Col_G containing numbers (pos or neg) or blanks, beginning in G3

Try this:
H3: =IF(G3=0,0,IF(G2="",H1,N(H2))-G3)

Copy that formula down as far as needed

Is that something you can work with?

Hi
I have a column "G" with negative numbers, positive numbers and
zero's.
Column "H" is the column that adds up all the negative numbers from
column "G" . When there is a positive number greater than zero i
need
column "H" to show a zero from the corresponding cell in column "G"
e.g
G H
-5.0 5.0
-5.0 10.0
-5.0 15.0
22.5 0.0

0.0 0.0
0.0 0.0
-7.0 7.0

42.5 0.0
-7.0 7.0
-8.0 15.0

-6.0 21.0
0.0 0.0
5.5 0.0

-12.5 12.5
-20.0 32.5
-8.0 40.5
