I am updating an assignment node by adding a formula for the Premise County field but since the field is a Picklist, I am getting the below error:
IF( not(isblank({!Existing_Contact_Loop.Premise_County__c})), {!Existing_Contact_Loop.Premise_County__c}, {!$Record.Premise_County__c} )
Please assist with how to edit this formula. Thanks.
