# Error handling

You can specify how a Vuser handles errors during script execution. By default, when a Vuser detects an error, the Vuser stops executing the script. You can instruct a Vuser to continue with the next iteration when an error occurs using one of the following methods:

- Using runtime settings. You can specify the Continue on Error runtime setting. The Continue on Error runtime setting applies to the entire Vuser script. You can use the lr_continue_on_error function to override the Continue on Error runtime setting for a portion of a script.

- Using the lr_continue_on_error function. The lr_continue_on_error function enables you to control error handling for a specific segment of a Vuser script. To mark the segment, enclose it with `lr_continue_on_error(1)`; and `lr_continue_on_error(0);` statements. The new error settings apply to the enclosed Vuser script segment. See the paragraphs below for details.

For example, if you enable the Continue on Error runtime setting and a Vuser encounters an error during replay of the following script segment, the Vuser continues executing the script:

        web_link("EBOOKS",
            "Text=EBOOKS",
            "Snapshot=t2.inf",
            LAST);
        web_link("Find Rocket eBooks",
            "Text=Find Rocket eBooks",
            "Snapshot=t3.inf",
            LAST);

To instruct the Vuser to continue on error for a specific segment of the script, enclose the segment with the appropriate lr_continue_on_error statements:

    lr_continue_on_error(1);
        web_link("EBOOKS",
            "Text=EBOOKS",
            "Snapshot=t2.inf",
            LAST);
        web_link("Find Rocket eBooks",
            "Text=Find Rocket eBooks",
            "Snapshot=t3.inf",
            LAST);
    lr_continue_on_error(0);
