ignore selection in the given set expression

[#1]

I am using the set expression to find out "Revenue" at "Latest Year":

=sum({1<Year={'$(=(max(num#(Year))))'}>}Revenue)

Now, I have a list box with a field Year, which is used in above expression too. I want that even if I select any value in that list box (that contains Year), the above expression must not change.

Can you please help?
