CakePHP confirmation popup not appearing - php

Question

When a user clicks a submit button a popup should appear asking them if they wish to submit the selection. I've been adding to the view, and I just noticed that although the form works properly, I no longer receive a popup asking to confirm the selection.
This consists of two tables. An upper one to display info where each row has a checkbox. The bottom table allows you to choose if you want to submit only selected checkboxes, or all of the rows in the table.
<table>
<?
echo $this->Form->create(null,array(
'onsubmit'=>'return confirm("Are you sure you want to archive?'));
?>
<th>Order ID</th><th>Order Date</th><th>Order Total</th><th>Status</th><th>View</th><th>Select to Archive</th>
<?php foreach ($orders as $order): ?>
<tr>
<td><?php echo $order['Order']['id'];?> </td>
<td><?php echo $order['Order']['date']; ?></td>
<td><?php echo $order['Order']['total'];?> </td>
<td><?php echo $order['Order']['order_status'];?> </td>
<td><a href="/orders/details/<?php echo $order['Order']['id']; ?>"/>View Order</a> </td>
<td><? echo $this->Form->checkbox('archive_value.', array('hiddenField' => false, 'value' => $order['Order']['id'])); ?></td>
</tr>
<?php endforeach; ?>
</table>
<table class = "table_order_status">
<tr>
<td width="350">
<?
echo $this->Form->input('archive_values', array('options' => $archive_options, 'value' => $select_value, 'name' => 'archive'));
?>
</td>
<td>
<?
echo $this->Form->end(__('Submit'));
?>
</td>
</tr>
</table>

Answer 1

You have a typo in the onsubmit option. Look at your quotes. Im guessing this line:
'onsubmit'=>'return confirm("Are you sure you want to archive?'));
should be:
'onsubmit'=>'return confirm("Are you sure you want to archive?")');
