# Display Dynamic Text

## Overview

You might want to show dynamic text on a step of your form depending on the collected form data or a custom logic rule. Alternatively, you might want to open a dynamic URL from your form or show a dynamic field tooltip.

To do so, you may include a text variable in your text with double curly braces like: `{{firstName}}`.

If the text variable matches the ID of a form or hidden field, Feathery will automatically populate it with the corresponding value. To populate the user ID of the current session, use `{{feathery_user_id}}`.

Aside from directly filling out fields in the form, you can also [manually set](https://docs.feathery.io/develop/react#setvalues) field values through [logic](https://docs.feathery.io/platform/build-forms/advanced-logic) or the [embed library](https://docs.feathery.io/develop/react) to populate text variables.

### Example <a href="#example" id="example"></a>

For example, you might need to display the input values from a calculator, along with the calculated total.
