How to limit appointment to once per day

Hi,
How can I set my date picker for one person per date?
I am wanting to make a signup form for volunteering for one person per date, how can I do that?

Hello Julia,

Thanks for reaching out to Jotform Support. Unfortunately, blocking out already selected dates using the date picker is not possible. I suggest using the appointment field instead, this would allow your responders to set up an appointment and not make that date available for others to take. Let me help you set that up:

• In Form Builder, click on the add element icon on the left side of the screen.
• Select the appointment field and it will be added to your form.
• Click on the appointment's gear icon to open it settings and click on the Availability tab
• Set the custom minutes to 480 so that only one appointment a day can be taken.

Give it a try and let us know how it goes.
