You can translate most of the form's validation texts from the setting:
🗄️ Old dashboard:
To start, edit your form in the Formaloo old dashboard and click on the “Design” tab. Open up the “Customize more content” option and change the text of the fields you want.
To change the “Submit” button, you should edit the “Submit button text” field below the form fields list.
To change the success message (the message shown after submitting the form), you should edit the “Success message after submit” text area below the form fields list.
