How do I add content to my right-hand column?

// get the data from the South Lacrosse server, caching results for 2 hours

$httpCache = new httpCache($xmlurl,$xmlfile);

$httpCache->fetch();



// parse XML data into arrays for easier processing

if (!$httpCache->isError()) {

	$parser = new simpleParser();

	$xml = &$parser->parseString($httpCache->getXml());

}



if ($httpCache->isError()) {

	echo '<p style="color: red;"><b>Error retrieving data : ' . $httpCache->getError()

		. "</b></p>\n"; 

} elseif (!$xml) {

	echo '<p style="color: red;"><b>Error converting data : ' . $parser->getError()

		. "</b></p>\n"; 

} else {

	// print heading for the division, and table heading for the league table for this division

	// Loop thru all the teams in the division, and print a table row for each team

	foreach ($xml->division->team as $team) {
