One way is to change your array layout like this
$helpsystem = array(
0 => array(
'title'=>'username',
'content'=>'The username that you choose must....'),
1 => array(
'title' =>'password',
'content'=>'The password that you choose must....));
Then it is easy to navigate as the next and previous will always be numerical
keys
