in the Load Script
I mentioned Variables like this
Let vmaxyear= 'max(Year)';
Let vpreyear='max(Year)-1';
so that in text object I wrote an expression like this
=sum({$ <$(vmaxyear) >}Sales) and
another text object expression like this
= sum({$ <$(vpreyear) >}Sales),
here I am getting same value for both the varaibles
Can you tell me how can I write an expression for
current year- previous year / previous year expression by using above variables
