How to link Database from home screen

Hi, I’m beginner, I’m trying to create a school app,my problem is I have created the database for the list on the home screen. But when previewing and I choose a course the database which is supposed to show on the course details isn’t featuring… I have already linked the home screen to the course details screen

How many screens are there? You probably have missing data from another screen, which doesn’t have the correct data, linking to the course details screen. All inbound links to a page must carry the relevant data for that data to be available.
