i have a budget for each months expenses. I wish to accumulate the monthly
costs each month by reference to the month I am working with. For example In
month 4 I need each amount appearing on each row to be added togethe, the
totals to appear in column 13. In month 5 I need the totals in column 13 to
represent the addition of each row in columns 1 through 5 and so on. The only
entry I wish to make is to record which month I am workingh with for
reference by the formula
