Issue with Product Variation Quantities

Hi all, I've implemented the e-commerce module, and am using product variations exclusively. Adding to cart works, but the +/- quantity functions are not working. The issue is: the ID in the add/remove link is the ID of the product, not the variation. I get the following error message as a result:

Fatal error: Call to a member function getQuantity() on a non-object in...

How would I go about pointing to the variation id, and not the product id?

Thanks in advance!
