how to insert page content from one page into another

I really have looked for this... I could swear I've done it before and it's totally simple, but maybe it's just Monday because I can't quite get it to fly.

Every page on the site has a sidebar. I have created a multi record sidebar and it's working on the testpage.

This is the testpage:
http://www.nwsc5872139.myutilitydomain.com/boxList.php

I would like to be able to pull that page into the sidebar of all other pages.

I've added this to both the boxList page and the news.php page - and it pulls the info if I repeat all the fields, but I was hoping to just "get" the page (boxList.php) instead.

// load records
list($boxRecords, $boxMetaData) = getRecords(array(
'tableName' => 'box',
'limit' => '3',
'orderBy' => 'RAND()',
));


I know this is the part I'm messing up: (in the news.php page - sidebar)

<?php foreach ($boxRecords as $record): ?>
<?php echo $record['list'] ?>
<?php endforeach ?>

<?php if (!$boxRecords): ?>
No records were found!<br/><br/>
<?php endif ?>

both boxList.php & new.php are attached. Thanks so much for your help!!
