Okay, what threw me (and the guy who entered in all the variants) was the sorting of the table on the variant setup page.
My thoughts:
For ease of use shouldn't the 'management' table sort order by variant group and then order by? Otherwise it's really ugly to manage multiple variant groups/names. Also, there needs to be an SKU for each variant.
Also, I'm not having any success getting the Variant Image to load in the cart when different variants are selected. That could be because the guy who entered all the variants thought sortorder was for Variant group display. After I've straightened some of them out, I still can't get images to load. Does the image uploaded under product setup override?
Thanks,
