In your “Clients” table, you have a person named “Robin”. In "Robin"s row, you’ll have a cell that links to all of "Robin"s financial records. Click/tap the +
button in that cell, and select “+ Add new record” at the bottom. A new Financial Record will expand, and it will automatically be linked to “Robin”. You can fill out all of the data, and then close it – after closing it, you will still be in the “Clients” table, and be able to see "Robin"s record, with his new Financial Record attached.
