1054 Unknown column 'p.products_sell_quantity' in 'field list'

Hi

I keep getting this error that says

1054 Unknown column 'p.products_sell_quantity' in 'field list'
in:
[select pd.products_name, pd.products_description, pd.products_url, p.products_id, p.products_quantity, p.products_model, p.products_image, p.products_price, p.products_virtual, p.products_weight, p.products_date_added, p.products_last_modified, date_format(p.products_date_available, '%Y-%m-%d') as products_date_available, p.products_status, p.products_tax_class_id, p.manufacturers_id, p.products_quantity_order_min, p.products_quantity_order_units, p.products_priced_by_attribute, p.product_is_free, p.product_is_call, p.products_quantity_mixed, p.product_is_always_free_shipping, p.products_qty_box_status, p.products_quantity_order_max, p.products_sort_order, p.products_discount_type, p.products_discount_type_from, p.products_price_sorter, p.master_categories_id, p.products_sell_quantity, p.products_less_quantity, p.products_coupon from zen_products p, zen_products_description pd where p.products_id = '8' and p.products_id = pd.products_id and pd.language_id = '1']
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields.

I have received the same error... I am copying a site and its contents to a new site - to a clean database ... I could just port over the old database as well and revise the configure.php files accordingly, however, I am up for the challenge here.. I used Easy Populate to populate the products... however, I need to manually adjust the attributes from new... How do I insert these fields into the database?

Please advise,

Eran

There is a mod called "Buy one Get one free" that uses this field. You need to run the sql script to create the database fields as part of the installation of this mod.
