# Log

The **Log** building block allows you to record custom log messages during a TaskBot's run. These messages are displayed in the running log dialog and saved in the Run Reports ([Using Run Reports](/using-zerowork/using-run-reports.md)) for future reference.

If no message is entered, a warning is recorded, but the TaskBot run remains unaffected and its status is not marked as failed.
