mysql - MySQL ERROR 1349 What I am missing?

Question

I am getting a MySQL 1349 error, but it appears as though the error is incorrect:

ERROR 1349: View's SELECT contains a subquery in the FROM clause

Can I not have ANY subqueries when creating a view?

Here is my SQL:

CREATE VIEW  `wordpress`.`ffi_be_v_book_details` AS (
  SELECT ffi_be_courses. * , COALESCE(  `Total` , 0 ) AS  `Total` 
  FROM  `ffi_be_courses` 
  LEFT JOIN (
    SELECT * , COUNT(  `Course` ) AS  `Total` 
    FROM ffi_be_courses
    RIGHT JOIN (
      SELECT  `Course` 
      FROM  `ffi_be_bookcourses` 
      LEFT JOIN  `ffi_be_sale` ON ffi_be_bookcourses.SaleID = ffi_be_sale.SaleID
      WHERE DATE_ADD( ffi_be_sale.Upload, INTERVAL( 
        SELECT  `BookExpireMonths` 
        FROM  `ffi_be_settings` ) MONTH ) > CURDATE( ) AND ffi_be_sale.Sold =  '0'
      GROUP BY ffi_be_bookcourses.SaleID
    ) AS  `q1` ON ffi_be_courses.Code = q1.Course
    GROUP BY q1.Course
  ) AS  `q2` ON ffi_be_courses.Code = q2.Code
  WHERE ffi_be_courses.Type =  'Arts'
  ORDER BY ffi_be_courses.Name ASC
)

Thank you for your time.
