OK, I give up!  I'm not sure what I am doing wrong!

I have the following script that determines the date and shows a 1 week Calendar.
The Next Week Button and the PREV week button work 100%.  However, depending on the day, there is a query that pulls information from a DB and displays it on the correct date. This also works 100%.  However, when I click NEXT or PREVIOUS the Calendar itself does not change date. (At line 38)

function weekCalendar($date='Today')	{  //  METHOD
    $pdo = new PDO("");
	$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
	
	
	
    $timestamp      = strtotime(date('Y-m-01', strtotime($date)));
    $caption     	= date("F Y", $timestamp);

	
	$date = !empty($_GET['d']) ? $_GET['d'] : 'Today';
	
	$ts = !empty($_GET['d']) ? strtotime($_GET['d']) : strtotime('Today');
	
	if (!$ts) $ts = strtotime('Today');
	$prev = date('Y-m-d', $ts - 60*60*24*7);
	$next = date('Y-m-d', $ts + 60*60*24*7);

	$prev_link = '<a href="' . $_SERVER['PHP_SELF'] . "?d=$prev" . '">Prev</a>' . PHP_EOL;
	$next_link = '<a href="' . $_SERVER['PHP_SELF'] . "?d=$next" . '">Next</a>' . PHP_EOL;
	
	$date_adv = date('Y-m', $ts);

?>

<table id="cal_nav">
	<tr>
		<td class="cal-nav-left"><h2><?php echo $prev_link; ?></h2></td>
		<td class="cal-nav-center"><h2><?php echo date('F Y', strtotime($date)); ?></h2></td>
		<td class="cal-nav-right"><h2><?php echo $next_link; ?></h2></td>
	</tr>
</table>

<?php	
    echo PHP_EOL;
	echo "<table class='full'><tr>";
	
	for($day=1; $day<=7; $day++) {
		echo '<td class="align-top"><strong>' .date('D M d', strtotime($date_adv.'-'.$day)).'</strong><br />';
		
		$this_date = date('Y-m-d', strtotime($date_adv.'-'.$day));
		echo $this_date;
		
		$sql = "SELECT schedule_id, first_name, last_name, asset_name, asset_type, start_date, workorder_id, color
				FROM schedule
				WHERE start_date = '$this_date'
				GROUP BY schedule_id DESC";

		$pdos = $pdo->prepare($sql, array(PDO::ATTR_CURSOR => PDO::CURSOR_SCROLL));
		
		try{
			$pdos->execute();
			
			if ($pdos) {
				while ($row = $pdos->fetch(PDO::FETCH_OBJ)) {
					$at = $row->asset_type;
					$fn = $row->first_name;
					$ln = $row->last_name;
					$sd = $row->start_date;
					$id = $row->schedule_id;
					$ac = $row->color;
 
					
					if ($sd == $this_date && $at == 'driver') {
						
						echo '<a href="view_workorder_print.php?id='.$id.'">'.$fn .''. $ln .'</a><br />';
						} 
					
				}  //  END WHILE
				
			}  //  END IF
			
			
		}  //  END TRY			          	
		catch(PDOException $e) {
   			echo 'ERROR: ' . $e->getMessage();
		}
		echo "<td>";	
	}  //  END FOR
	echo "</tr></table>";
		
	}
//  END WEEK CAKENDAR
