# Warning Messages

In the Warning Messages tab, you can set custom warning messages to guide users when required fields are missing or invalid inputs are detected. The tab is divided into two sections and they contain several settings inside.

{% hint style="info" %}
You can make the field required in the settings of the [**element.**](/cost-calculator-builder/calculator-elements/general-overview.md)
{% endhint %}

## **Error Messages in Contact Forms**

This section lets you define custom error messages for fields within [**order forms**](/cost-calculator-builder/cost-calculator-settings/calculator-settings/order-form.md), ensuring users provide all required information accurately. You can set specific warnings for missing or incorrectly formatted inputs such as email, name, phone number, or terms and conditions acknowledgment. These messages guide users through completing the form correctly and prevent submission errors.

* **Email Format Message -** set the warning message shown when an invalid [**email**](/cost-calculator-builder/cost-calculator-settings/in-builder-setting/form-manager.md#email) format is entered (e.g., "Invalid email").
* **Email Required Message -** define the error message for missing [**email**](/cost-calculator-builder/cost-calculator-settings/in-builder-setting/form-manager.md#email) input (e.g., "Email is required").
* **Name Required Message** - specify the message displayed when the [**name field**](/cost-calculator-builder/cost-calculator-settings/in-builder-setting/form-manager.md#name) is left blank (e.g., "Name is required").
* **Phone Required Message** - customize the notice for missing [**phone number**](/cost-calculator-builder/cost-calculator-settings/in-builder-setting/form-manager.md#number) input (e.g., "Phone number is required").
* **Terms and Conditions Required Message** - create a message prompting users to check the [**terms and conditions**](/cost-calculator-builder/cost-calculator-settings/calculator-settings/order-form.md#terms-and-conditions-agreement) box (e.g., "Please, check out our terms and click on the box").
