Problem s prenosem formu

Cest chlapi, uz nevim co,tak pisu sem, tenhle zdrojak obsahuje form, kterej vola sam sebe,ale kdyz se zavola,tak se neprenesou udaje $nick,$name, jediny co se prenese je $email... nerozumim tomu... dik za rady

-jinak head() a foot() obsahujou jenom zacatek a konec hmtl stranky...
- buttonek() akorat zavira celou stranku

<?
include "../function.php";
include "../conn.php";

$error = ''; // promìnná obsahuje pøípadné chybové hlášení

// editace uživatele
if ($email != "" && $pass != "" && $nick != "" && $name != "")
{
if (!isset($deny)) $deny = 1;

@$sql = mysql_query("SELECT * FROM users WHERE nick LIKE '$nick'");
if (mysql_num_rows($sql) > 0)
{
$login = '';
$error = "<DIV ALIGN=CENTER>Login již existuje !!!</DIV>\n";
}
else
{
// pøidáme uživatele
@$sql = mysql_query("INSERT INTO users VALUES (null,'$nick','$name', '".md5($heslo)."','$email',
'$deny','$poz')") or die(mysql_error());

mysql_close($conn);
zavri();
exit;
}
}

// databázi již nebudeme potøebovat
mysql_close($conn);

head()
?>

<H4 ALIGN="CENTER"><B>Editace uživatele</B></H4>

<? echo $error; ?>
