The comments aren't displaying???

[cturner]

After adding a comment I try to view the comment and it just displays a blank page. Can someone please tell me why and how I can fix? Thanks in advance.

Here is the code to add a comment:
[code]
require "config2.php";
$arrErrors = array();

// the publish button
if (isset($_POST['publish'])) {
// if comment field is empty display a message
if ($_POST ['comment'] == '') {
$arrErrors['comment'] = 'Please enter a comment.';
}

// if no errors insert data into database
if (count($arrErrors) == 0) {
// get the id number
$articleid = mysql_real_escape_string($_GET['articleid']);
// get the user's username that made the comment
$username = mysql_real_escape_string($_COOKIE['username']);
// get the comment from the form
$comment = mysql_real_escape_string($_POST['comment']);
// get today's date
$date_entered = date("j F, Y");
$date = mysql_real_escape_string($date_entered);
// insert the articleid into the commentpost table
$insert = "INSERT INTO `commentpost` (`id`, `articleid`, `comment`, `date_entered`, `username`) VALUES (0, '$articleid', '$comment', '$date', '$username')";

if (mysql_query ($insert)) {
// once the data has been added go to the comment_added page
header ('Location: comment_added.php');
} else {
print "<p>Could not add the entry because: <b>" . mysql_error() .
"</b>. The query was $insert.</p>";
}

} else {
// The error array had something in it. There was an error.
    // Start adding error text to an error string.
    $strError = '<div class="formerror"><p>Please check the following and try again:</p><ul>';
    // Get each error and add it to the error string
    // as a list item.
    foreach ($arrErrors as $error) {
$strError .= "<li>$error</li>";
}
    $strError .= '</ul></div>';
}
}
[/code]

Here is the code to view the comments:
[code]
require "config2.php";
$articleid = mysql_real_escape_string($_GET['articleid']);

// select the articleid
$query = "SELECT * FROM `commentpost` WHERE `articleid` = $articleid";
$result = mysql_query ($query) or die("Could not query because: " . mysql_error());

while($row = mysql_fetch_array($result)) {
// print the comments for that article and the date entered and the username
echo "<br /><br />".$row['date_entered']."<br />".$row['comment']."<br />";
echo $row['username']."<br />";
}

mysql_close();
[/code]

try checking to see how much rows you are getting:
[code=php:0]echo "Rows Found: ".mysql_num_rows($query);[/code]

I have placed that into my code to view the comments and it displays 0 rows. What I am wanting to know is why does it displays 0 rows when I have just added a comment for that article?

try echoing out $articleid and see if it is actually set. if it is set then go into phpMyAdmin and view the comments table and look for the record you just added. check that the articleid matches the one in your link.
