I am trying to sell a t-shirt with S,M,L,XL sizes. Everything seems to work properly until I do an "Add to Cart". No matter what size I select, the cart only shows the product with no variation indicated at all.
If I select a different size and "Add to Cart" a second time, all it does is update the quantity of the first product in the cart. There's no way to tell that I wanted to order a single Small and a single Large, rather than two of no size at all!
I know it should work, because I've seen the correct behavior in the demo store before I bought this plugin. :) Is there something I'm doing wrong? I've tried following the various tutorials repeatedly, and I can't see anything in my settings that looks incorrect.
