I am using the code below to send emails out to a mailing list using PHPmailer. right now i cant get the code to work. is the way im doing it correct or is there a better way. the code below is a cobmination of code ripped from another app and my own code.

if ($_POST[issending] == "yes"){
	$eventTitle = $_POST['eventTitle'];
	$eventId = $_POST['eventId'];
	$eventMessage = $_POST['eventMessage'];
	$runningtally = $_POST['runningtally'];
/////////////////send the emails out///////////
///counter sets the start point of query
///count is running tally of emails sent
///count2
    $count=0;

include("inc/MailerClass.php");
//require ("inc/MailerClass.php");

$mailer = new eMailer;

$mailer->Subject = "YOU HAVE BEEN SENT AN INVITATION FROM ". $config['sitename']."";
// HTML body
$htmlBody  = "$lang[email_sentmessage]: $eventTitle\n";
$htmlBody .= "$eventMessage\n";
$htmlBody .= "$lang[email_msg1]\n\n";
$htmlBody .= "$config[installdir]/viewevent.php?eventId=$eventId\n";
$htmlBody .= "$lang[email_msg12]";

// Plain text body (for mail clients that cannot read HTML)
$textBody  = "$lang[email_sentmessage]: $eventTitle\n";
$textBody .= "$eventMessage\n";
$textBody .= "$lang[email_msg1]\n\n";
$textBody .= "$config[installdir]/viewevent.php?eventId=$eventId\n";
$textBody .= "$lang[email_msg12]";

$mailer->Body = stripslashes($htmlBody);
$mailer->AltBody = stripslashes($textBody);
$mailer->IsHTML(true);  
//$mailer->WordWrap = 75;
$mailer->UseMSMailHeaders = true;
$mailer->AddCustomHeader("X-Mailer:  Email Interface");


echo "<b>Send Newsletter</b><br><br>\n";

if ($runningtally == "") {
$runningtally=0;
}

$query = "SELECT * FROM usereventmap WHERE eventId='$eventId' LIMIT $runningtally, 2";
$result = mysql_query($query) or die("<b>aaaA fatal MySQL error occured</b>.\n<br />Query: " . $query . "<br />\nError: (" . mysql_errno() . ") " . mysql_error());

while ($row = mysql_fetch_array($result)) {
    if (! get_cfg_var('safe_mode')) {
    	set_time_limit(0);
    }

	$userarray = getUserInfo ($row['userId']);
    $mailer->AddAddress("$userarray[emailAddress]","");


    if(!$mailer->Send()) {
		echo "There was an error sending the message to ". $userarray['emailAddress'] ." !!!<br>";
    } else {
	echo "Mail to ".$userarray['emailAddress']." <b>sent</b>!<br>";
    }

    flush();
    $mailer->ClearAllRecipients();
    echo "count before $count<br>";
    echo "count2 before $count2<br>";
    echo "counter before $counter<br>";
    $runningtally++;
    $count++;

 	if ($count == 2) {
		echo "<small>... sending in progress - please be patient ...</small>";
		echo "<form method=\"POST\" name=\"form\" id=\"form\" action=\"$PHP_SELF\">
    	    <input type=hidden name=\"issending\" value=\"yes\">
    	    <input type=hidden name=\"runningtally\" value=\"$runningtally\">
    	</form>
    	<script language=javascript>document.form.submit();</script>";
	}else {
		echo "DONE sending emails";
	}
}//end while

}else{
do something
}

echo "<br>$runningtally emails sent.<br>\n";
