Smart List Validation Error

Version 2

    Issue Description
    You encounter Validation Errors in the Smart List.


    Issue Resolution
    If you hover your cursor over the red squiggle in the Smart List, Marketo should pop-up a reason why the error is occurring.


    A very common reason for Validation Errors is when using an "is" logic for a constraint, the value being used does not exist in the database.


    In situations where you are uncertain if the exact value exists in the database, it's suggested that you utilize "contains" for the constraint logic.
