i have problem in mysql code. not allow me import sql file , give me error " #1215 - cannot add foreign key constraint "

i have no ideea do. searched here, tried examples this: mysql error: cannot add foreign key constraint? no succes.

you need use of primary key columns on fk references.

should be
