Working on Comment System

I have most of my comment system done, but I am having problems with the posting to database for some reason. It keeps saying: Error: You have an error in yoru SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax use near " at line 1.

I think it is because of me trying to send nid. It doesnt seem to be posting it. If you would like to see for yourself try here: http://www.omniboggle.com/ then comment on the first post and just put in jibberish.

Here is the code for comments.php


<?php

ini_set ('display_errors', 1);
error_reporting (E_ALL & ~E_NOTICE);

if (isset($_POST['submit'])){
	if ($dbc = @mysql_connect ('localhost', '*****', '*****')){
		if (!@mysql_select_db('omniboggle')){
			die('<p>1. Error</p>');
		}
	} else {
		die ('<p>2. Error</p>');
	}
	
	$query = "INSERT INTO comment (id, name, n_id, n_title, comment, date_entered)
			 VALUES (0, '{$_POST[name]}', '{$_POST[nid]}', '{$_POST['title']}', '{$_POST['comment']}', NOW())";
	
	if (@mysql_query($query)){
		$success = true;
	} else {
		$success = false;
		echo "3Error: " . mysql_error() . "";
	}
	
	mysql_close();
	echo "$success";
}
?>

Here is function gtitle()


function gtitle($nid)
{
	error_reporting (E_ALL & ~E_NOTICE);
	if ($dbc = @mysql_connect('localhost', '****', '****')){
		if (!$dbc = @mysql_select_db('omniboggle')){
			die('<p>Error: ' . mysql_error() . '</p>');
		}
	} else {
		die('<p>Error: ' . mysql_error() . '</p>');
	}
	$query = "SELECT title FROM news WHERE id = $nid";
	if ($r = mysql_query($query)){
		while ($row = mysql_fetch_array($r)){
			$title = $row['title'];
		}
	} else {
		die('<p>Error: ' . mysql_error() . '</p>');
	}
	mysql_close();
	
	return $title;
}
