Hi,
Might be that the value for the "products_cost" is missing.
insert into products (products_quantity, products_model, products_image, products_price, products_cost, products_date_added, products_date_available, products_weight, products_status, products_tax_class_id, manufacturers_id) values ('1000', '', 'emergen-cimmunedefense.jpg', '430.0000', '215.0000', now(), null, '0.00', '0', '0', '0')
