I've got a spreadsheet that tracks a number of inventory categories & values
by month. The last column calculates the Monthly Change for each row - this
month's inventory minus last month's inventory. Rather than change the
formula each month I thought I could use a nested IF based on the month
number, but ran into the limitation of 7 nested IFs, which is a problem given
that there are 12 months. Anyone have a good way to do a subtraction
calculation in a cell that will have varying column references each month?
Thanks
