Check your contact file.

Structure

• My Contacts.fmp12 is a separate practice file.
• Contacts is the table name.
• FirstName, LastName and Email are Text fields.
• The default primary key and creation/modification fields are preserved.

Practice

• Linh Nguyen, Alex Rivera and Alex Morgan each have one record.
• The generated IDs are non-empty and different.
• Sam Patel was added as a fourth record.
• Sam’s email was changed to sam.patel@example.com without changing the ID.
• The four records remain after closing and reopening the file.
