    Hi Gil,

    Trying to learn PowerBI, and this is a great walkthrough, but as soon as I invoked the function, I got an error I couldn’t resolve…

    “Formula.Firewall: Query references other queries or steps, so it may not directly access a data source. Please rebuild this data combination.”

    When I download the solution, I get the same error in both ‘People’ and ‘Species’ queries.

    What might be happening here?
