Hello,

I'm trying to automate a method of summing across columns. To be
exact, let's say I have 5 columns (A B C D E), the first of which
MIGHT contain a negative value (it may also contain a positive value,
and B C D E might have a zero or some positive value. What I want to
do is... IF A has a negative value I want it to add it to E (to reduce
it), if E becomes zero and there is still some left from A, I want it
to add the remainder to D... then C.... then B. Essentially I want
the values of E D C B to be reduced, in turn, by the value that is in
A (but only if A has a negative value).

I'm hoping this makes sense... and I'm hoping someone out there can
figure this out.

Cheers.
