To exclude a filter with an if

[Aika]

Hello,
I have a filter to which a condition is applied:
if(pkeysPENLS=0,Null(),[action_date.autoCalendar.Year])

I have to exclude this filter from a measure:
Sum({$<[action_date.autoCalendar.Year]=>} collections)

but it does not work. What is the right syntax?
Thanks!
