Unable to derive date difference in Document of Records DFF using Value Set

Summary:

The system should calculate the trip duration (number of days / nights) based on the difference between these two dates and store/display it in a separate field.

In a Document of Record , the user enters:

• Start Date
• End Date

The system should calculate the trip duration (number of days / nights) based on the difference between these two dates and store/display it in a separate field at real time when change date.

• any solution to solve or workaround

Appreciate your support ASAP.
