Hi t_akiyama,

Thanks for reaching out to Jotform Support. Our Japanese Support agents are busy helping other Jotform users right now, so I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in Japanese, let us know and we can have them do that. But, it might take a while until they're available again.

Now, coming back to your question, I'll need some time to look into this. I'll get back to you as soon as I can.

We appreciate your patience and understanding.

Hi t_akiyama,

You can add a Paragraph element showing your preferred Error message. But, you also have to add a Short Text field where we can pass the value of the Name field. Let me show you how to do this:

1. In Form Builder, click on Add Element on the left side of the page.
2. From the Basic tab, select Short Text and Paragraph.
3. Click on the Gear icon of the Short Text element.
4. From the General tab, enter your preferred Field Label.
5. From the Advanced tab, toggle Hide Field.
6. Click on the Pencil icon of the Paragraph element.
7. Enter your preferred message and click on the Check icon to Save the changes.

Let's now pass the value of the Name field to the Short Text element by setting up an Update/Calculate Field condition:

1. In Form Builder, click on Settings on the orange navigation bar at the top of the page.
2. Select Conditions from the left side window.
3. Select Update/Calculate Field.
4. Set up the condition like the one below and click on Save at the bottom of the page.

Let's now set up a Show/Hide Field condition:

1. Still on the Conditions page, select Show/Hide Field.
2. Set up the condition like the one below and click on Save at the bottom of the page. In the Value field, enter all the list of the Katakana Alphabets.

Here's the result:
