    1. Hi Simon,

      Yes, you can change any error message on the form.

      To do that, you need to go to Form Settings –> Translations.

      Once you are there, add the English language for example, and click on customize.

      A lightbox will pop-up and in that lightbox, you should see the tab for System Messages.

      Simply right in the box next to the Message what you want to see instead and hit save.

      If you experience any issues or difficulties, please contact support either through Live Chat or at support@123formbuilder.com

      Have a great day!
