If there is an error occurs in any step during a task, RoboTask records an error message to the task log and stops the task by default. You can change this behavior. To do it, you should select the "Advanced" tab in the task editor and set the "If Error Occurred" parameter to "Continue Execution". In this case, the task will not be stopped in case of an error.
The system variable {IsError} is used to analyze if there was an error in the previous step. This variable contains "True" if there was an error in the previous step and "False" if there was no error in the previous step.
