I need help finishing the integration of Google Checkout and Google Base Feeder into my Zencart application. I already have Google production and sandbox accounts and have tried to get both add-ons to work but have been unsuccessful. I get the following error message when trying to use Google Checkout:
1054 Unknown column 'products_sell_quantity' in 'field list'
in:
[select products_id,products_sell_quantity,products_less_quantity,products_coupon from prefix_products order by products_id]
This occurs when I click the" Add to Cart" button.
Google Base Feeder shows up under "Configuration" but not under "Tools".
