We sell one product split into multiple bag sizes. On the product page, we need users to be able to select various quantities of each size that will add up to the total they need (and eventually, I hope, a calculator that will do it for them). I am having toruble figuring out how to do this in woocommerce.
Essentially, I want it to look/work like this: http://www.pinnaclerubbermulch.com/store/product_info.php?products_id=28
Am I on the right track by trying to use variations to accomplish this, or am I missing some other feature (or plugin) that will let me do it?
Thanks for any help you can offer.
