Hi,

Have a problem hopefully I can get some help with. I need a formula to find
the last positive number in a row and then add that and all the numbers that
come after it.

Example:

-10 100 -10 -20 60 -10 -20

I need the formula to locate the 60 and then add 60+(-10)+(-20)

Thanks in advance!

Rich

Hi Rich,

Assume your data is in A1:A7
In A2 enter this formula:
=IF(A10,0,A1)
In B2, enter this formula:
=IF(B10,0,A2+B1)
copy this formula to the right as far as you need

Although not perfect given there could be all positive numbers something on
these lines would give you the result :

=SUM(OFFSET($A$1,MATCH(2,1/(--(A1:A70))),,ROW(A7))) array entered
(ctrl+shift+enter)
