# How to Add Custom Fields to the Checkout Page
Custom fields let you ask customers questions when they wrap up their orders, such as "How did you find us?", "What products are you interested in?" and "How was your shopping experience?"
**Setting Up Custom Fields**
To configure custom questions using Volusion's Custom Fields functions:
1\. Log in to your Admin Area and go to **Settings** \> **Custom Fields**.
2\. Click on the ID number of a custom field entry to edit an existing field or click **Add** to create a new one. There are two types of custom fields that can be created: **Customers**-based, which provide questions asked once when a customer registers with the store and **Orders**-based which present questions to customers each time they create an order.
3\. Select a field type from the **Table Name** menu.
4\. In the custom field's settings, set **Alias** to something related to the question (for example, "HowFound" if the question is "How did you find us?")
5\. Enter the appropriate question in the **Question** field (for example, the prompt the customer sees, such as "How did you find our site?")\*
6\. Optionally, you can enter additional text into the **Question Sub Text** field to provide customers an instructional prompt for the custom field (for example, suggested answers). This is displayed after the field.
7\. Now, select the **Input Type**:
- **Textbox**: to provide a textbox customers can type a response into
- **Checkbox**: to provide options for users to click on (such as "I agree to these terms")
- **Dropdown**: to provide a drop-down list of possible responses
8\. Enter a value for the **Input Max Length** field to define the maximum number of characters customers can enter in the textbox. This is a required field, so you must enter a value even if you selected the **Checkbox** or **Dropdown Input Type**. In these cases, the value you enter has no impact on the field.
9\. Enter a numeric value into the **Placement Order** field to define the order in which this field will appear, in relation to any other custom fields you create.
10\. Check the **Is Required** option to force customers to enter some value into the custom field.
11\. Enable the **Is Public?** option to display this custom field to customers. Uncheck to hide. The default is hide.
12\. Click the **Show On Invoices** option if you want to display the content of all custom fields on a customer's invoice.
13\. When finished, click **Save**.
**\*** While the **Question Subtext** field supports HTML, the **Question** field does not. The following characters are not valid in the **Question** field, and may cause errors at checkout: " \> \< ; '
**Dropdown Options**
Note that if you choose the **Dropdown** input type, a list of options for the drop-down menu must be provided for customers to choose from. To do this, click on the **Filter** menu on the **Custom Fields** table and choose **Custom Fields Dropdown Values**.
Click **Add** to begin creating a drop-down field value.
1. From the **Custom Fields ID** menu, select the custom field you wish to apply the drop-down option to.
2. Enter a **Title** for this option. This is what will be displayed in the drop-down list.
3. Enter a **Value**. This is the value that will be recorded when this option is selected.
4. Enter a numeric value into the **Placement Order** field to define where this option will appear within the drop-down list.
5. Click **Save** to create the value.
Repeat this process to create additional drop-down values.
**Customer Responses**
Both Customer and Order fields are displayed on the checkout page. The Customer fields, however, are only displayed during a customer's first order.
After the first order has been placed, the customer's responses to the Customer custom fields can be found in their account page, in the **Custom Fields** section.
The responses to the Order custom fields are displayed in the associated order page, in the **Marketing** section. Note that these can be changed on this page.
If you select **Show on Invoices** for any of these fields, the **Question** and the **Response** is displayed in a section entitled Additional Information at the top of invoice. For drop-downs, the **Question** and **Value** display.
Please note that customers may receive an error upon checkout if the text they input into the custom field exceeds the Input Max Length character limit.
Note there can be a maximum of 15 custom fields in your store. This can be 15 custom order fields, 15 custom customer fields, or a combination of both.
