Paginate by Category

I am working on a site for a foundation. One of the tables is for grants that they have given out in the past. The first criteria for sorting the list is by the quarter in which they were given (date_awarded). The list is going to get quite lengthy so I would like to only display the grants from one quarter at a time - the most recent first. I would then like to have a drop down menu for selecting a different quarter which would then show only those grants given in the selected quarter.

A live version of the page is posted here:
http://www.buhlfoundation.org/whatwedo/recent-recipients.php

The drop down is generated from the db, but I can't seem to get it to work.

Viewer code...
<?php

require_once "/data/16/1/154/52/1806867/user/1957059/htdocs/cmsAdmin/lib/viewer_functions.php";

list($past_recipientsRecords, $past_recipientsMetaData) = getRecords(array(
'tableName' => 'past_recipients',
'loadUploads' => '0',
'allowSearch' => '1',
'where' => 'showonsite=1',
));

?>

Form Code...
<form method="GET" action="recent-recipients.php" style="background: #eee; padding: 7px 10px;margin: 0 0 20px">
<label>Show Grants From Another Quarter:</label>
<select name="date_awarded_keyword">
<?php foreach ($past_recipientsRecords as $record): ?>
<?php if ($record['date_awarded'] != @$boardMtgdate): ?>
<?php $boardMtgdate = $record['date_awarded']; ?>
<option value="<?php echo ($record['date_awarded']) ?>"><?php echo date("F j, Y", strtotime($record['date_awarded'])) ?></option>
<?php endif ?>
<?php endforeach; ?>
</select>
<input type="submit" name="submit" value="Submit" />
</form>
