I am using a very easy formula to add certain numbers across a spreadsheet.
It has worked fine for each line until I reached one line where the
formula
doesn't work - Even though I have the formula as sum of certain functions
on
that line (as I do in other lines of the spreadsheet), I get the sum of
numbers in this column added down to this line. And the lines after this
particular again use my formula. It is making me craxy.
