From the above diagram, can anyone help me with a formula for Accumulated cell in Last Year? Basically, this auto sum has to correspondence with the figures entered into This Year cells (ie. if 2 cells have figures, the Accumulated cells in Last Year will sum up 2 cells only and so forth)
Please help.
