parse error in categories

Hi, thanks for the prompt reply

here is a piece of the code:

<?php
global $wp_query;
$image_width = get_option(‘product_image_width’);
/*
* Most functions called in this page can be found in the wpsc_query.php file
*/
jQuery(function($) {
$(“form.product_form, .wpsc-add-to-cart-button-form”).die(‘submit’).live(‘submit’, function() {
return confirm(‘Proceed to Checkout?’);
});
});
?>

The code was like this from the beginning.
Some categories work fine and the products in these categories are displayed on the site.

But some categories only diplay the product, when there is only 1 product in this category. When you add another product, the before mentioned error appears on the site.

So, why does it only work fine for some categories?

The code is part of the products_page.
The plugin we use is WP-ecommerce.
I am also going to post the problem on the wp-ecommerce site.

Thanks for the advices so far.
