is shown when I execute this script

while($row = mysql_fetch_array($query))
  {
    $email = $row ['rvalue'];
echo "$email <br/>";
{$sql =( "SELECT message.body
             FROM message
             JOIN recipientinfo
             ON message.mid = recipientinfo.mid
             WHERE message.sender = 'john.arnold@enron.com'
		 AND recipientinfo.rvalue = '$email'
             AND recipientinfo.rtype = 'TO' ");
		 $query = mysql_query ($sql)or die("Query:<br>{$query}<br>Error:<br>".mysql_error());
             $show = mysql_num_rows($query);
             echo "$show <br/>"; }

  }

It means exactly what is says. $row['rvalue'] does not exist.
