Hey Brian,
Thanks for the response. It's a static, string parameter that should allow for multiple selections. I've attached a screenshot. Ideally, the user should see 89 selections when they select this parameter in the report.
I moved the logic to the Selection formula but I had to remove the "else" in your second line because it was giving me an error about a "number, current amount, boolean is expected here".
But after doing this, the incentive parameter is still not appearing in the where clause when I look at the SQL code.
