did you open and look at the table called "products_attributes". if you look in the table you will see the attributes for your products...in your post before the last one you asked if there is a mathmatical formula that correlates one set of attributes to another. there is no formula...there is this table. so to "predict" what the values should be, look in this table for the product_id you want...then find the option_id's for the options you want to add...and then you can lookup their product_attributes_id and put it in the stock_attributes column on the products_with_attributes_stock table.
