# FORM Butler – Custom validation messages

Create custom messages on your form-field validations. Use translations to serve your customers in their preferred language.

[Custom and translated message](https://assets.pdfbutler.com/website/academy.folders/FORM%20%20Butler%20-%20Custom%20and%20translated%20error%20messages.pdf)

Next to custom messages per FormField, you can also have generic translated messages for all validation instead of declaring a validation message per FormField.

In the message, you can use [[!FIELD!]] and [[!MF!]]

On the Translation DataSource, you can use following translation keys:

- validation_REQUIRED: generic translation for the "required" validation eg "The field [[!FIELD!]] is required"
- validation_EMAIL
- validation_MIN_LENGTH
- validation_MAX_LENGTH
- validation_MIN_VALUE
- validation_MAX_VALUE
- validation_DATE
- validation_PATTERN
- captcha-incorrect
