Forms can be set to expire after a specified amount of time. Expired forms are not accessible by website users.
To set an expiration date for a form, click the "Scheduled" radio button in the "Activation" section of the left-hand of the Build & Edit tab.
Use the "Start" and "End" fields to pop open the Date & Time Picker calendar. Select the time frame for which the form should be active.
Click the "Save" button when finished. The Activation section will indicate that an activity period has been set.
Outside of the specified date range, the form will display the expiration message. This message can be customized in the Form Layout section at the top of the Build & Edit tab (click the "Show" link to reveal the "Expired form message" field).
