[php]$selector = '.'.strtolower(str_replace(' ', '-', str_replace('&', '_', $category['category_name'])));[/php]
with this one
[php]$catname_replace = array("&", ",", "'");
$selector = '.'.strtolower(str_replace(' ', '-', str_replace($catname_replace, '_', $category['category_name'])));[/php]
and in files
