a10coker on "Error when restoring database with phpmyadmin"

I made a backup .sql file of my wordpress database. When I use phpmyadmin to try and import the database file, I get the error message below.

Error
SQL query:

--
-- Database: wordpress
--
-- --------------------------------------------------------
--
-- Table structure for table wp_commentmeta
--
CREATE TABLE wp_commentmeta (

meta_id BIGINT( 20 ) UNSIGNED NOT NULL ,
comment_id BIGINT( 20 ) UNSIGNED NOT NULL DEFAULT '0',
meta_key VARCHAR( 255 ) COLLATE utf8mb4_unicode_ci DEFAULT NULL ,
meta_value LONGTEXT COLLATE utf8mb4_unicode_ci
) ENGINE = INNODB DEFAULT CHARSET = utf8mb4 COLLATE = utf8mb4_unicode_ci;

The settings used for the phpmyadmin import:
