I'm creating a variable called property_address that is concat of address_line_1, address_line_2, city, state, zip.
Sometimes address_line_2 is blank, and since I am using concat, there is an extra comma ',' in the property address.
Is there a way to use an if statement or some other function inside the filter to make it so that the concat only runs if address_line_2 is empty to make it so there is not an extra comma?
