Due Date Based On Start Date Automation

[Shaakirah Muhammad]

I would like to set an automation in my Trello board to automatically set the due date on each card for 30 days from the start date of that card. I tried using "when custom field "date" is set, set due date on the date in custom field "date", and set due date on the date in custom field "date" plus 30 days" and "when custom field "date" is set, and set due date on the date in custom field "date" plus 30 days", but the due date is not setting.

This is the Date field I'm referring to:
