You just need to do another join to the employee table.
$sql_notes = "SELECT notes.assembly_notes,
notes.assembly_notes_contact_id,employee.name " .
"FROM t_product AS prod, t_link_product_assembly_notes
AS link, t_assembly_notes AS notes,t_employee as employee " .
"WHERE link.product_id = prod.product_id " .
"AND link.assembly_notes_id = notes.assembly_notes_id".
"AND notes.assembly_notes_contact_id=employee.employee_id".
"AND link.product_id = " . $product_id;
You will, of course, have to change the table names, etc. to match your
table descriptions.
