How can I disable the same timeslot in the appointment when it was already booked at the other appointment?

These are great, but there is one big issue with the scheduling update - if you have someone book their second dose appointment it doesn't show that time as booked in the first dose calendar. For example, I created a test form where it has both a first dose appointment field and a second dose appointment field. I used the logic as recommended and it worked great. I set the first appointment as April 5 at 11am and it automatically modified the second dose appointment field to be 28 days after the first dose, so I scheduled the second dose on May 3rd at 11am. After submitting, I went back in to the form but I could still book a new first dose appointment on May 3rd at 11am. Ideally, we want to have the option to not book two people on the same day at the same time unless we change the settings to 'Group' instead of 'One-on-one'. Is there a way to fix the appointment fields to talk with each other and/or combine them in to one calendar?

We apologize for the inconvenience.

Once the form is submitted, the selected timeslot should no longer be available. Would you mind if we will submit your form to test this out?

If you look at the following screenshot, you can see that the target date cannot be selected:

For as long as the appointment exists in your submissions, one should not be able to select it from the calendar.

I'm sorry, I got it wrong. I see you're trying to disable the same timeslot in the 1st dose calendar when it is already booked at the 2nd dose. I'll see if it's possible.

Thanks

I'm sorry, but I found no workaround to accomplish this. You may opt to use a single appointment field and ask users to submit the form twice—one for their 1st dose and another one for their 2nd dose.

Thanks
