Hi Tony,
i had added some new fields to product by using my custom module and follow your doc
http://devs.x-cart.com/en/basics/model_editing_page.html in X-Cart Business 5.2.13
when i upgrade X-Cart Business 5.2.13 to X-Cart Business 5.3.1.2, product fields are here but not show into admin area. While in old version (X-Cart Business 5.2.13) its working fine. Fields are showing and we can can edit its value
please let me know how get my custom fields and it value into admin area on product edit page.
Thanks
