little error in capcha user guide

[eluser]SPeed_FANat1c[/eluser]

Code:

CREATE TABLE captcha (
captcha_id bigint(13) unsigned NOT NULL auto_increment,
captcha_time int(10) unsigned NOT NULL,
ip_address varchar(16) default '0' NOT NULL,
word varchar(20) NOT NULL,
PRIMARY KEY `captcha_id` (`captcha_id`),
KEY `word` (`word`)
);

Code:

// Then see if a captcha exists:
$sql = "SELECT COUNT(*) AS count FROM captcha WHERE word = ? AND ip_address = ? AND date > ?";

there is no such column "date"

First: check your captcha directory to 777 access
Second: install php-gd
