Format Numbers cell to auto enter the number in the cell above +1 in each new row
I am trying to create a formula to have the cells in column A auto populate with 2020-XXX, with the XXX being the end number in the cell directly above it. Column A row 1 is 2020-001, Column A row 2 would then be 2020-002 etc..
I have tried a number of different formulas but none work. Has anyone accomplished this before and if so would you be willing to share the formula?
Thanks
AJ
