Background Color expression by date

[QlikSenseUser2]

I'm trying to set a Background Color expression by date. I want it to show green if within a year of the LAST_INSPECTION_DATE  or Red if greater than a year of the LAST_INSPECTION_DATE.

I have 

IF(Year(Aggr(max(LAST_INSPECTION_DATE),TRAILER)) > AddYears(Aggr(max(LAST_INSPECTION_DATE),TRAILER),1), LightRed(),Green())

And I get this all green
