need a code script modified.
you will see in the attached that the formula is summing the wrong columns. it is supposed to look for when the array crosses 215,000 of the sum of the preceding columns, then take the sum of all of the next columns . for some reason it starts an n+1, n+2 instead of summing n,n+1,n+2...i.e. it skips the cell immediately following the cell where threshold was crossed.
