Hi @Ireland12345,
You can achieve this with a formula field and a simple update record automation, rather than going down the script route.
- Create a formula field “End Calculation”, with the following formula: DATEADD({Appointment Date}, 30, 'minutes'). In the field’s formatting tab, be sure to turn off “Use the same time zone for all collaborators”
- Create a “When record is updated” automation to trigger when your Appointment Date field is updated. Have an update record step that sets your End Time field to your End Calculation value.
This way allows you to manually alter your end time, if you need to the flexibility for your appointments to be longer than 30 min. If you don’t and they will all always be 30 minutes, you can do without the automation altogether and just use step one & have a calculated End Time.
