<div id="catcontainer">
<div class="cat_navigation">
<div class="wrapper">
        <ul id="catbar">
<?php $exclude = $myOptions['cat_excl'];?>
<?php if(!$myOptions['cat_limit']) {
$limit = '10'; } else {
$limit = $myOptions['cat_limit'];
}</blockquote>
if($myOptions['cat_limit'] == '0') {
$limit = 0;
}
?>
	<?php wp_list_categories("exclude=$exclude&title_li=&depth=2&number=$limit"); ?>
	</ul>
