Hi,

I have an urgent question:

say i have the following data:

a1 = -1, a2 = 0, a3 = -2, a4 = 1, a5 = 2, a6 = -1, a7 = -2, a8 = 5, a9
= -1, a10 = 1

I want to add the first consecutive positive numbers. How do I write a
formula for it?

What I want Excel to do is to go through this and add a4 and a5, that
is it. Those are the first cosecutive numbers that appear in the data
set.

Try this in B2 and copy down:

=IF(AND(MAX(B$1:B1)=0,MIN(A1:A2)0,A2=A1+1),A1+A2, "")
