So, I'm painfully new at all of this. The last time I even thought about playing around with websites, angelfire was the new hotness and everyone was getting in on some sixdegrees...

Well, I'm trying to learn by doing, but I've ran into a roadblock. I'm attempting to make a simple random quote generator. I've got the MySQL db made, configured, and user set. I decided to try to make a form so populating it would be easier. When I load the URL for the form, I get this error:

Access denied for user 'dbusername'@'localhost' (using password: YES) in /home/hostusername/public_html/quoteform.php on line 18

Here is the code I'm using:

<form action="" method="post"> 
<fieldset> 
<legend>Add a Quote</legend> 
<label for="quote">Quote:</label> 
<input type="text" name="quote" id="quote" maxlength="1500" /> 
<label for="author">Author:</label> 
<input type="text" name="author" id="author" maxlength="60" /> 
<input type="submit" value="Add Quote" /> 
</fieldset> 
</form> 

<?php 
$user="mydbusername"; 
$password="dbpw"; 
$database="dbname"; 
$connection = mysql_connect('localhost',$user,$password); 
@mysql_select_db($database) or die( "Unable to select database");

if ($_REQUEST['quote'] != "") { 
 if($_REQUEST['author'] != "") { 
  $author = $_REQUEST['author']; 
 } else { 
  $author = "Anonymous"; 
 } 
 $quote = $_REQUEST['quote']; 
  
 $query="INSERT INTO `quote` (`quote`,`source`) values ('" . mysql_real_escape_string($quote) . "','" . mysql_real_escape_string($author) . "')"; 
 $result = mysql_query($query) or die(mysql_error()); 
 echo("inserted quote: " . htmlentities($quote) . " by " . htmlentities($author) . " into database"); 
} else { 
 echo("<p>Please enter a quote and author</p>"); 
} 
?> 

Now, I freely admit to having ganked this code off of a blog (I would include the blog's url, but I'm not sure if that's kosher.) in an attempt to learn by fiddling with, but I'm at a loss.

Oh, I've a shared host at hostgator if that makes any sort of difference.

Thanks
