## How to pre-fill a field

Click a field's <Icon icon="gear-complex" iconType="solid" />. In the right-hand panel, fill out the **Default value** with a text or hover and click <Icon icon="square-plus" iconType="solid" /> to reference a value. Fillout lets you map:

* <Icon icon="file-lines" iconType="solid" /> - [answers to another Fillout field](/help/answer-piping) including [respondent info from a login step](/help/login-page)
* <Icon icon="link" iconType="solid" /> - [URL parameters](/help/url-parameters)
* <Icon icon="calculator" iconType="solid" /> - [calculations](https://www.fillout.com/help/calculations#pre-fill-fields-with-a-calculation)
* <Icon icon="calendar" iconType="solid" /> - [custom dates](/help/pre-fill-dates)
* <Icon icon="user" iconType="solid" /> - [enriched emails](https://www.fillout.com/help/lead-enrichment#how-to-enrich-emails) with company information
* <Icon icon="pen-to-square" iconType="solid" /> - [static values](/help/integration-static-values)
* <Icon icon="database" iconType="solid" /> - database records

For example, the customer’s name is set as the default invoice addressee, since this is often the case, but they can change it if needed.

## Pre-fill with external data

You can also pre-fill fields with data from external sources like Airtable and Notion. Here's an example of referencing data from the Airtable record the form is editing. Check this [guide](/help/fetch-dynamic-data).
