warning errors when viewing categories

[KirstyBurgoine]

Hi,

I am using osCommerce version 2.2rc2a on a site I'm building and I keep getting these warning messages when I click on a category.

 

Warning: Division by zero in /home/sites/airchilled.co.uk/public_html/catalog/includes/modules/product_listing_col.php on line 140

 

Is this just because I have no sub categories and the level of error reporting is set too high? or is there something wrong with my installation?

 

You can view the errors at www.airchilled.co.uk/catalog/ then click on the category Beetles 1.

 

Thanks

 

Kirsty
