need help with checkbox

[eluser]webstudent_101[/eluser]
well i have this in my view..

<?= form_open('merchant/result')?>
<? foreach($employees as $item):?>
&lt;?= form_checkbox('employee', $item->user_firstname)." - ".$item->user_firstname; ?&gt;<br/>
&lt;? endforeach;?&gt;
&lt;?= form_submit('submit', 'enter')?&gt;
&lt;?= form_close();?&gt;

and in the 'merchant/result' i wanted to get all the checked employee.. but every time i check all the last employee will be the only one to show.. is there a way to make the checked items an array or something? ive been searching the internet for quiet some time about codeigniter and multiple checked items with no possible aid ti my problem..

thanks alot.. and tnx in advance
