I'm making a model where I need to use a certain years in a bunch of expressions. For example:
""era_2" > YEAR1"
"era_2" > YEAR2 AND "era_2" < YEAR1
"era_2" >= YEAR3 AND "ERA_2" <= YEAR1
It's confusing at the moment for other people using the model. So is there a way I can use an input number in the expression?

"era_2") in your expression, or the year number variables (YEAR1,YEAR2,YEAR3)? – csk Feb 21 '20 at 18:22
