Creating tables help!!

I am trying to create a table for my plugin. When I check phpmyadmin — I don’t see the table listed, therefore assume the table hasn’t been created. Here’s my code:

function immune_install () {
global $wpdb;
global $immune_db_version;

$table_name = $wpdb->prefix . “release_list”;
if($wpdb->get_var(“show tables like ‘$table_name'”) != $table_name) {

= $releasetable = “CREATE TABLE “. $table_name . ” (
id mediumint(9) NOT NULL AUTO_INCREMENT,
release_title text NOT NULL,
release_date mediumint(9) NOT NULL,
release_label text NOT NULL,
release_format text NOT NULL,
release_link text NOT NULL,
);”;

require_once(ABSPATH . ‘wp-admin/includes/upgrade.php’);
dbDelta($releasetable);
}
}

Thanks!!
