Need Help with Quantity for Product Attributes

[Guest]

Hello,

 

I installed this add-on (http://addons.oscommerce.com/info/3302) so I can specify different quantities for the product attributes of an item. When I try to edit in my admin panel the quantity, I get this error:

 

1054 - Unknown column 'options_quantity' in 'field list'

 

update products_attributes set products_id = '94', options_id = '1', options_values_id = '1', options_values_price = '0.0000', price_prefix = '', options_quantity = '5' where products_attributes_id = '39'

 

[TEP STOP]

 

Does anyone know why this is happening and how to fix this? Thank you very much in advance.
