Translating specific error message

I couldn’t find the error message that occurs when the information of the form isn’t provided properly. Can I personalize it somewhere? If not a better grammatically correct translation for the error message would be:
In Ihrem Formular sind Fehler aufgetreten. Bitte korrigieren Sie diese bevor Sie fortfahren.
instead of:
In Ihrer Form sind Fehler. Bitte beheben Sie diese bevor Sie fortfahren.

Hi Holger,

I presume that you would like to translate this warning: "There are errors on the form. Please fix them before continuing."

To do so please follow this guide: How to Change/Translate Form Warnings

This will show you the list of the warnings and if you can not find the one you want, just click on CTRL + F and a search bar should appear and as you type it should take you to the first matching text.

Do let us know if you have any further questions.

Best Regards,
Ben
