Captcha helper problem

[eluser]mi6crazyheart[/eluser]
Try to use this piece of code instead of u'r code...

Code:

// Then see if a captcha exists:
$sql = "SELECT COUNT(*) AS count FROM captcha WHERE word = ? AND ip_address = ? AND captcha_time > ?";
$binds = array($captcha, $this->input->ip_address(), $expiration);
$query = $this->db->query($sql, $binds);
$row = $query->row();
