Yes, all the fields display fine everywhere else - product pages, cart, checkout - just not views.

I think I may have tracked it down to the fact that I'm using revisions on my site. Because of this, the vid and nid for a product are different. If I go into the node table in my database and set a product's vid to be equal to the nid, the fields will show up in views. (Of course, this messes up everything else - the product page, cart, add to cart link...). It doesn't help if I just create the product with "Create new Revision" off, because the nid and vid in the node table will already be different.

Does that make sense? Could views be trying to pull the sell_price and other fields from the uc_products table with the vid, when it should be using the nid??

This type of debugging is pushing the bounds of my experience with drupal, so my apologies if this is unclear or confusing...

Thanks for your help.
