Problema para cadastrar dados no BD

Olá pessoal, eu estou com um problema na página que recebe os dados e insere, o código ta assim

<meta charset="UTF-8">
<?php
include("config.php");

$nome=$_POST['titulo'];
$usuario=$_POST['descricao'];
$senha=$_POST['code'];
$email=$_POST['Usuario'];

#//retirando espaços

$erro=0;

if($erro==0){

#//inseri no banco de dados se tudo for OK

 $i=mysql_query("INSERT INTO code_block (titulo, descricao, html, usuario) VALUES ('$nome','$usuario','$senha','$email')");
 mysql_select_db("linkmrcx_m") or die(mysql_error());

	//query SQL
	$result = mysql_query("SELECT * FROM code_block ORDER BY id DESC LIMIT 5"); // SQL PARA OBTER OS 5 ULTIMOS ID's!

while ($row = mysql_fetch_array($result)) { // Executa a query (o recordset $rs contém o resultado da query)

// Encerra a conexão

 echo '<h1>Bloco Salvo!</h1>';
 $strName='Meu Bloco';
 $strLink = "<a href = 'http://linkmrc.x10.mx/block/" . $row['id'] . "'>" . $strName . "</a>";

 // Lista de links
 echo "<li>" . $strLink . "</li>";

}

mysql_close();

	?>

Só que aparece um erro que diz:

Parse error: syntax error, unexpected $end in /home/linkmrcx/public_html/code_block_submit.php on line 174.Só que a linha 174, é o fechamento da tag <style>, oque eu faço?

$nome=$_POST['titulo'];
$usuario=$_POST['descricao'];
$senha=$_POST['code'];
$email=$_POST['Usuario'];
 

 

 

$nome recebendo um $_POST titulo

 echo"<script type='text/javascript'>";
