I have created column 1,2,3,4 divide I need to do the calculations in back end based on divide values.
For column 1 need to put value constant divide value for 12.
and if value is 24 then need to make calculation for volumn 1 for 24 is
value for 1 for 24=(value for column 1 for 12+value for column 1 for 24)/2
value for 1 for 36=(value for column 1 for 12+value for column 1 for 36)/2
value for 1 for 48=(value for column 1 for 12+value for column 1 for 48)/2
for 2,3,4 need to show rolling values based on divide value 12.
for eg-
value for 2 for 12 = value for column 2 for 12
value for 2 for 24 = value for column 2 for 12+value for column 2 for 24
value for 2 for 36 = value for column 2 for 12+value for column 2 for 24+value for column 2 for 36
