## Ask your assistant

- "Add a phone number field after the email field."
- "Make the budget field required and add an option for over 50k."

Every field has a stable **key** (like `budget_range`) that your assistant uses to target edits — you never need to know it, just describe the field by what it asks.

- **Add**: "add a company-size choice field with 1–10, 11–50, 50+" — one or many at once, at any position.
- **Edit**: labels, help text, required, options, number/rating bounds, [AI follow-ups](/help/adaptive/ai-follow-ups) and [validation](/help/adaptive/semantic-validation).
- **Reorder / remove**: "move email to the top", "remove the fax field".

A form holds up to 60 fields across up to 20 steps — see [limits](/help/limits). If an edit is invalid (duplicate options, a rating span over 10), the assistant gets an actionable error and fixes it. Edits to a published form go live when you republish.

## FAQ

**What happens to existing responses when I change fields?**
Responses are kept. Removing a field does not delete answers already collected; republish to make edits live for new respondents.
