Last two corrections are:
ALTER TABLE `test_apptest`.`Rights` ADD CONSTRAINT PRIMARY KEY (ID);

ALTER TABLE `test_apptest`.`Roles_have_Rights`
ADD CONSTRAINT `fk_Roles_have_Rights_Rights1`
FOREIGN KEY (`Rights_ID`)
REFERENCES `test_apptest`.`Rights` (`ID`)
ON DELETE NO ACTION
ON UPDATE NO ACTION,
ENGINE = InnoDB;

ALTER TABLE `test_apptest`.`Countries` ADD CONSTRAINT PRIMARY KEY (ID);

ALTER TABLE `test_apptest`.`States`
ADD CONSTRAINT `fk_States_Countries1`
FOREIGN KEY (`Countries_ID`)
REFERENCES `test_apptest`.`Countries` (`ID`)
ON DELETE NO ACTION
ON UPDATE NO ACTION,
ENGINE = InnoDB;

With this modification to my SQL script, THE PROBLEM IS SOLVED.
