SELECT multiple columns

[Adam 552]

<?php
$result = mysql_query("SELECT army FROM users WHERE username = '$username'");
if (!$result) {
    echo 'Could not run query: ' . mysql_error();
    exit;
}
$row = mysql_fetch_row($result);
$cheese = mysql_query("SELECT username, xcounits, ycounits, points FROM users WHERE army = '$row[0]' LIMIT 0 , 1000");
if (!$cheese) {
    echo 'Could not run query: ' . mysql_error();
    exit;
}
$toast = mysql_fetch_row($cheese);
echo '<B>';
echo $toast[0];
echo '</b>';
?>

OK, I have got a problem... for some reason when I use the script above it only displays the persons username. Why not the xcounits,ycounits and points? Also this will show anyone whos in the same 'army' as this user.
