Hello Mr. Larry Ullman.
I am reading your book PHP and MySQL for Dynamic Web Sites: Visual QuickPro Guide , and i´m beginner of php language and a big fan of your work, that is well done, with a clear language and explanations well explicated.
Althought i follow all the steps of the chapter 19 of the Example of E-commerce, my database of E-coomerce gave me some errors (see the attached file). Also I put the scripts of the example of your book.
I don´t know how to solve the problem, please could you help me?
I using the xampp software and phpmyadmin to build the database of the e-commerce.
Best regards.
Ps.: Below i sent you the scripts of the tables of the database.
