Create a validation rule to check that a contact is in the zip code of its account.

I'm creating validations for the formulas and validations module and I'm currently doing the challenge. The directions are a little confusing and I just received this error: "There was an unexpected error in your org which is preventing this assessment check from completing: System.DmlException: Insert failed. First exception on row 0; first error: FIELD_CUSTOM_VALIDATION_EXCEPTION, Mailing postal code must match the account's shipping postal code.: []"

    Hi Legend,

     

    Could you please try the formula below 

    AND(
      NOT( ISBLANK( AccountId ) ),
      MailingPostalCode <> Account.ShippingPostalCode
    )

     

    Kindly let me know if this works :D

     

    Thanks
