FCK Form 1Additional field problem

Using FCK with PHP, i have strange error - can any one tell me what is wrong?
Below my code.

if (isset($_POST))
   $postArray = &$_POST ;         // 4.1.0 or later, use $_POST
else
   $postArray = &$HTTP_POST_VARS ;   // prior to 4.1.0, use HTTP_POST_VARS

foreach ( $postArray as $sForm => $value )
{
   if ( get_magic_quotes_gpc() )
      $postedValue = htmlspecialchars( stripslashes( $value ) ) ;
   else
      $postedValue = htmlspecialchars( $value ) ;

if (isset($_POST))
    {

// --------------------------------------- Script update (inserting news in to mysql)

    $KolejnyID = mysql_query('SELECT id,tekst,tytul FROM '.$Tabele.' ORDER BY id DESC ');
    $ID = mysql_fetch_array($KolejnyID);
    $PlusJedendoID = $ID['id']+1;
    $Zachowaj = mysql_query("INSERT INTO $Tabele(id,tekst,tytul) VALUES('$PlusJedendoID','$value','$_POST[tytul]') ") or die('Blad');
    $KolejnyID = mysql_query('SELECT id,tekst,tytul FROM '.$Tabele.' ORDER BY id DESC ');
    $ID = mysql_fetch_array($KolejnyID);
    $Identyfikator = $ID['id'];
    $Wybierz = mysql_query('SELECT id,tekst,tytul FROM '.$Tabele.' WHERE id = '.$Identyfikator.' ORDER BY id DESC');
    $ObecnaTresc = mysql_fetch_array($Wybierz);
// --------------------------------------- Script update (inserting news in to mysql)
    }
}
