# Warning Texts
In the Warning Texts 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.
## Error Message in Calculator
This section is responsible for setting up warning messages in the calculator input fields.
* **Required Field Notice -** customize the message displayed when a required field is left empty (e.g., "This field is required").
{% hint style="info" %}
You can make the field required in the settings of the [**element.**](https://docs.stylemixthemes.com/cost-calculator-builder/calculator-elements)
{% endhint %}
## **Error Messages in Order Forms**
This section lets you define custom error messages for fields within [**order forms**](https://docs.stylemixthemes.com/cost-calculator-builder/cost-calculator-settings/calculator-settings/order-form), 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 Notice -** set the warning message shown when an invalid [**email**](https://docs.stylemixthemes.com/cost-calculator-builder/cost-calculator-settings/form-manager#email) format is entered (e.g., "Invalid email").
* **Email Required Notice -** define the error message for missing [**email**](https://docs.stylemixthemes.com/cost-calculator-builder/cost-calculator-settings/form-manager#email) input (e.g., "Email is required").
* **Name Required Notice** - specify the message displayed when the [**name field**](https://docs.stylemixthemes.com/cost-calculator-builder/cost-calculator-settings/form-manager#name) is left blank (e.g., "Name is required").
* **Phone Required Notice** - customize the notice for missing [**phone number**](https://docs.stylemixthemes.com/cost-calculator-builder/cost-calculator-settings/form-manager#number) input (e.g., "Phone number is required").
* **Terms Required Notice** - create a message prompting users to check the [**terms and conditions**](https://docs.stylemixthemes.com/cost-calculator-builder/cost-calculator-settings/order-form#terms-and-conditions-agreement) box (e.g., "Please, check out our terms and click on the box").
