Creating Simple First Master Detail Page Help Required

Content

Hi,

I have a Master Record Table with below Line Items are already appearing in a List View. Now I have added a "Add Create Page" button on my Line Items List View to add more Line records. 

When I press Add Create Button, on the next page foreign key does not populate from the previous records (Master OR Line). How can i populate my foreign key on next Create page from previous page?

 

Regards,

Zahid Rahim
