Adding user fields into author template

Hello All

I am modifying my author template to include fields such as ICQ #, AIM, YIM, MSN screen names. The only field that I could get working was the user web site. The other fields do not populate even though I see it when I go to edit my profile.

Here is the code from my author template

<?php get_header(); ?>

<?php
global $wp_query;
$curauth = $wp_query->get_queried_object();
?>
<div id="content">
<table border="0" cellpadding="0" cellspacing="0"  bordercolor="#FFFFFF" width="100%">
<tr>
<!--User Details Block-->
<td width="120" valign="top" align="left">

<?php
if(isset($_GET['author_name'])) :
$curauth = get_userdatabylogin($author_name);
else :
$curauth = get_userdata(intval($author));
endif;
?>
<BR />Website:
<a href="<?php echo $curauth->user_url; ?>">WEBSITE</a><br />

<strong>ICQ #:</strong>
<?php echo $curauth->user_icq; ?><br />
<strong>AIM:</strong>
<?php echo $curauth->user_aim; ?><br />
<strong>MSN:</strong>
<?php echo $curauth->user_msn; ?><br />
<strong>Yahoo:</strong>
<?php echo $curauth->user_YIM; ?><br />
