# Answer piping

> Use previous answers or inputs to control logic, personalize your form, or show read-only fields.

## What is answer piping?

**Answer piping** displays a respondent's previous form inputs into texts or read-only fields for a more personalized and interactive experience. Fillout lets you reference:

* <Icon icon="file-lines" iconType="solid" /> - [previous answers](/answer-piping)
* <Icon icon="link" iconType="solid" /> - [URL parameters](/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](/pre-fill-dates) (e.g., today, a month from now, etc.)
* <Icon icon="user" iconType="solid" /> - [enriched emails](https://www.fillout.com/help/lead-enrichment#how-to-enrich-emails) with company information
* <Icon icon="database" iconType="solid" /> - database records

## Reference field labels

To reference previous form inputs in headings, paragraphs, and banners, type **@**. Then, select the field or question, or simply search for it.

## Reference integration records

If your form is set to [update an existing record](https://www.fillout.com/help/airtable-update-form#how-it-works) in an integration (e.g., in Airtable or HubSpot), you can display values from that record in your form.

In your heading or paragraph, type **@**. Then, click <Icon icon="database" iconType="solid" /> followed by `Updating records` to choose the field you'd like to display.

In our example, we'll reference a client's name and project details.
