I imported my products using node import, but it did something funny, apparently, because this module worked like a champ when I entered a product with attributes by hand, both import and export.
Thanks for your help David,
I thought it was funny too that the skus didn't come up in the stock either. I'll post this on the forums for node import with ubercart as well. Node import saw the options you tell it to bring in, but must mess up the sub-skus. Even when you go to set the alternate skus on the edit page and set the alt skus they do not map properly and show up in the stocks.csv. thanks again,
