Yes, problem solved, thanks. Only now there's a small other problem. In the Hikashop/ Content Module, when displaying all products from a category, the link to the product page is not shown when there's no main price on the productpage (only prices assigned to the variants) and it displays the text "Free product". It will display after checking the "Add to shoppincart for free products", but I don't want that. It worked fine whith the former version (before you made the change for the SHIPPING-INVOICE problem). It just did show the "standard" variant then.
