Undefined index

Hi All,

I'm getting error:
Notice (8): Undefined index: Audit [APP\views\audits\indexsln.ctp,
line 32]
Notice (8): Undefined index: Endpoint

the codes are

index.ctp:

<?php
$options = array_combine ($a_eid, $a_sln);
//$form->create('audits'
echo $form->create('Audit', array( 'controller' => 'audits',
'type' => 'post', 'action' => 'indexsln'));
echo $form->select('endpoint_id',$options);//,null,null,false);
echo $form->submit('ok');
echo $form->end(); ?>

audits_controllers :

function indexsln() {
$id = $this->data['Audit']['endpoint_id'];
echo $id; //$sln;

$this->set('audits',$this->Audit->query(
"SELECT * FROM audits,endpoints WHERE endpoint_id
in
(SELECT id FROM endpoints WHERE sln in
(SELECT sln FROM endpoints WHERE id = ".$id."))
AND audits.endpoint_id = endpoints.id "));

$data=$this->paginate($this->Audit->read());
}

indexsln.ctp :

<div class="audits index">
<h2><?php __('Audits');?></h2>
<p>
<?php
echo $paginator->counter(array(
'format' => __('Page %page% of %pages%, showing %current% records out
of %count% total, starting on record %start%, ending on %end%', true)
));
?></p>
<table cellpadding="0" cellspacing="0">
<tr>
<th><?php echo $paginator->sort('id');?></th>
<th><?php echo $paginator->sort('endpoint_id');
?></th>
<th><?php echo $paginator->sort('day');
echo $paginator->sort('date');?></th>
<th><?php echo $paginator->sort('author');?></th>
<th><?php echo $paginator->sort('description');?></th>
<th><?php echo $paginator->sort('action');?></th>
<th><?php echo $paginator->sort('visible');?></th>
<th class="actions"><?php __('Actions');?></th>
</tr>
<?php
$i = 0;
foreach ($audits as $audit):
$class = null;
if ($i++ % 2 == 0) {
$class = ' class="altrow"';
}
?>
<tr<?php echo $class;?>>
<td>
<?php echo $audit['Audit']['id']; ?> // line 32
</td>

debuger result example:
