# Bookings must have notes

This validation rule prevents customers from placing a booking unless they have added notes. Admins can still book for customers without adding notes.

---

1. Log in to [dashboard.nexudus.com](https://dashboard.nexudus.com/) if you aren't already.
2. Click [**Settings > Validation rules**](https://dashboard.nexudus.com/settings/3/0/0).
3. Click **Add rule**.
4. Click on **Manual entry**.
5. Name your validation rule.
6. Add a **Description** for your rule to let other admins know what it does at a glance.
7. Toggle on **This rule is active**.
8. Select **Bookings** under the **Record type** drop-down list.
9. Add the **Error message to display if the validation rule is not met**.
10. Add the following code snippet to the **Formula** field.

```
record.Coworker = null OR record.Notes <> null
```

Want to also prevent admin from placing bookings without any notes on the Admin Panel?

Use the following snippet instead:

```
record.Notes <> null
```

1. Click the **Save Changes** button.

All done! We recommend testing the validation rule by logging in to the Members Portal with a dummy customer account and trying to book a resource without adding any notes. You should see your error message if the rule is working as expected.
