Thanks!

Can I add multiple code extracts here and if so is there an upper limit?

i.e.

// set cookies unique to certain products:
if ($current_page_base == 'product_info' && $_GET['products_id'] == '32') {
// do code here to set cookie
}
if ($current_page_base == 'product_info' && $_GET['products_id'] == '33') {
// more code here to set cookie
}
//

thanks
