Apologies if this has been posted in the wrong area.
I set up attributes for drop-down boxes, but when I try to run this in Attributes controller I get the following error message:

1054 Unknown column 'attributes_price_factor_onetime' in 'field list'
in:
[insert into products_attributes (products_attributes_id, products_id, options_id, options_values_id, options_values_price, price_prefix, products_options_sort_order, product_attribute_is_free, products_attributes_weight, products_attributes_weight_prefix, attributes_display_only, attributes_default, attributes_discounted, attributes_image, attributes_price_base_included, attributes_price_onetime, attributes_price_factor, attributes_price_factor_offset, attributes_price_factor_onetime, attributes_price_factor_onetime_offset, attributes_qty_prices, attributes_qty_prices_onetime, attributes_price_words, attributes_price_words_free, attributes_price_letters, attributes_price_letters_free, attributes_required) values (0, '1623', '1', '1', '0', '+', '0', '1', '0', '+', '0', '0', '1', '', '1', '0', '0', '0', '0', '0', '', '', '0', '0', '0', '0', '0')]
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.

Can anyone tell me where I am going wrong?

I set up both Option name and Option value before using the controller to attatch the attribute to a product. Basically, i just wanted a Size dropdown (sml/med/lrge) but the error keeps appearing.

Thanks for any help you could offer me.

many thanks
