AbleCommerce Shopping Cart Software

I'm new with this forum and would like to know if anyone can assist me with a Google Feed. I'm trying to learn how to upload my inventory to Google and have had some success but not as much as I would like. After a upload I'm getting an error with Google saying I have Invalid Indentifiers which is the UPC numbers that is not even in my a feature that I have with my shopping basket. Google is saying that my SKU number is the UPC number. What do I have to do to correct this problem? I haven't even attempted yet to upload to Shopping or Yahoo yet.
Thanks,

Google changed the feed definition after Able 7 was written and the feed generation code is a part of the API that can't be changed. In the Able generation the SKU is put into the UPC field. You can open the file in a spreadsheet and change the name in the header to something like model_number or delete that column. It might be fixed when Able 7.2 comes out.
Here are the Googlebase feed requirements.
