thank you so much for your reply. it did not work. the issue is the denoimator is the sum of 2016,2017 and 2018
but what I want is is 2016m2017 and 2018 selected. the denominator will be
for 2016- sum of 2016
2017 -sum of 2017
2018- sum of 2018
my formular is total claim on line item/total claim on total column.
total claim on total column is the denominator and it should be the total of one year /that year only. not the sum of the 3 years.
I really have no idea how to fix this.
