Hello,

I have a table that looks like this:

----------------------------
   A   B   C   D   E
1.                       8
2.  6   3   4    3    2
3.           Output: 3
---------------------------

The output value should show the number of columns (starting from E2
going to the left) it takes to add until the value (of the figures in
row E) is higher than E1.

In this case that would be 2 + 3 + 4 > 8, therefore the output would
be 3.
If E1 is 13, then the output would be 5, etc.

This formula is used to calculate the number of months of expenses to
replace an inventory figure.

Thanks for your time.
