I dont understand what you mean for that I think I have problem with my expresion
for skipped Just Year='2014'
and for globality my function is calcul if
year is 2014 Calcule is ('2014'/2013)-1 I use above for not calculed 2013 because I haven't
and if year='2015' calcul is (2015/2014)-1
and if year='2016' calcul is (2016/2015)-1
and if year='2017' calcul is (2017/2016)-1
