Hi, I have installed version 1-10-2 of base feeder on a v1.3.8a site (I know I should upgrade) and have resolved all the issues (thanks to previous posts). I have also installed the stock_by_attributes_1-4-13 which I got from the add-ons. Am I right in thinking that work is being done on how to incorperate gtin numbers for each attribute. As each product colour I sell has its own gtin number and currently I can only put one gtin number in the product field.
