Nie dodaje rekordu ;x

[Intelactive]

Witam. Jestem pewien , że skrypt działa w 100%.

Kod PHP:

<?PHP
                                $formularz = '
                                <form action="?do=add_comment" method="post">
                                <input type="text" name="add" value="Dodał"><br />
                                <textarea name="text" cols="65" rows="3">Treść komentarza. Max. 255 znaków.</textarea><br />
                                <input type="submit" name="submit" value="Dodaj">
                                </form>
                                ';
                                                                $add = addslashes(htmlspecialchars($_POST['add']));
                                $text = addslashes(htmlspecialchars($_POST['text']));
            
                                
                                if(isset($_POST['submit'])) {
                                $zapytanie = @mysql_query("INSERT INTO comments SET article_id='$id', text='$text', add='$add', data=now()");
                                echo mysql_error();
                                echo '<br>Pomyślnie dodano komentarz!';
                                } else {
                                echo $formularz; }
                                
                                ?>

Struktura tabeli:

Kod PHP:

CREATE TABLE `comments` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `article_id` int(11) NOT NULL,
  `title` varchar(50) NOT NULL,
  `text` text NOT NULL,
  `add` varchar(50) NOT NULL,
  `data` datetime NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 AUTO_INCREMENT=12 ; 


Błąd:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'add='Dodał', data=now()' at line 1

Hmm, co jest nie tak?
