Hi, maybe I missing something but did not you forget to declare the variable code right here: ``` if (last_result.length > 20) { code = order_by_occurrence(last_result)[0]; ``` should not it be: ``` if (last_result.length > 20) { var code = order_by_occurrence(last_result)[0]; ``` All the best. Thanks for this amazing video
