Oscommerce Expert - Quantity Price Breaks Contrib

Ok - I have a heavily modified site that has been in operation for over 2 years. I attempted to install the Price break contribution ([login to view URL],1242) But I continue to receive this error: 1054 - Unknown column 'p.products_price1' in 'field list' select p.products_id, pd.products_name, pd.products_description, pd.products_comments,p.products_model, p.products_quantity, p.products_image, p.products_subimage1, p.products_subimage2, p.products_subimage3, p.products_subimage4, p.products_subimage5, p.products_subimage6, pd.products_url, p.products_price, p.products_price1, p.products_price2, p.products_price3, p.products_price4, p.products_price5, p.products_price6, p.products_price7, p.products_price8, p.products_price1_qty, p.products_price2_qty, p.products_price3_qty, p.products_price4_qty, p.products_price5_qty, p.products_price6_qty, p.products_price7_qty, p.products_price8_qty, p.products_qty_blocks, p.products_tax_class_id, p.products_date_added, p.products_date_available, p.manufacturers_id from products p, products_description pd where p.products_id = '1194' and pd.products_id = '1194' and pd.language_id = '1' Yet, I clearly have the column 'products_price1' in the column, so it must be a deeper issue. I have this contribution fully installed, and my site mirrored to another domain, so you can work freely. Once problem is solved, it is up to me to transfer fix to live site. We would like to get started immediatly. Please, bid only if your sure you can solve this. It is not as simple as inserting the field in the database, as it is already there.
