Is there something wrong with my syntax?

Below is my script to create a table. I keep getting a syntax error.

CREATE TABLE products ( id int(11) NOT NULL auto_increment, product_name varchar(255) NOT NULL, price varchar(16) NOT NULL, details text NOT NULL, stock int() NOT NULL, category varchar(16) NOT NULL, subcategory varchar(16) NOT NULL, date_added date NOT NULL, PRIMARY KEY (id), UNIQUE KEY product_name (product_name) ) ;

The is the syntax error I get. You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘) NOT NULL, category varchar(16) NOT NULL, subcategory varchar(16) N’ at line 6.

Can someone please tell me what I am doing wrong. I don’t see it. And reading the error message obviously isn’t helping.
