どちらから設定を行えばよろしいでしょうか？

Hi kounotakanobu,

Thanks for reaching out to us for help. Unfortunately, our Japanese Support agents are currently busy helping other Jotform users at the moment. I'll try to assist you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd prefer to receive support in Japanese, let us know and we can have them do that. But, keep in mind that you'd have to wait until they're available again.

Unfortunately, the layout or design of the error message screen can not be changed, but text content of the Error message can be changed, Please follow the steps below and screencast:

• Click on the Setting on the Orange navigation bar at the top of the page.
• In the menu that opens on the left side of the page, click on Form Settings.
• Click on Show More Option Button.
• Click on the Edit button beside the Form Warning option.
• Update the Warning Message.
• Scroll down to the End and click on Save Changes Button to Save it

To know more about it please check this guide: How-to-Change-Form-Warnings.

If you need further assistance, please let us know.
