# Perform a new set of actions when an error occurs

In case your agent encounters an error while it's processing a web page—usually the *Element Not Found* error—you can configure the agent to run a different set of actions, rather than just stopping. This is especially useful when harvesting data from websites that use different layouts within a series of web pages. It gives you the ability to handle the page differences on a case-by-case basis.

You can define error handling in two places in the Agent Builder:

- The Action Properties panel (which can be done at any time).
- The Error Handling panel when an error occurs.

### The Action Properties panel

1. Right-click an action you want to add error handling to, then select **Properties** > **ERROR HANDLING**.

1. In the left panel, select:

- **Existing Page** if you have already created a page with the alternate actions you want to perform.
- **New Page** if no alternate actions have been created for the current web page.
