QTpro for OsCommerce 2.3.1 Track and manage attribute stock. You need this if you sell 1 items with various attributes, and you want to control stock on attribute level. I have uploaded the package here for it to appear in add-on section for 2.3 version. This is just a re-post, so all credits go to original poster. 2.2 version here: http://addons.oscommerce.com/info/888 And support thread for it here: http://forums.oscommerce.com/topic/31484-contribution-qtpro-quantity-tracking-professional/page__hl__qtpro The uploaded file and instructions was installed on a almost clean 2.3.1 install (only a handfull other mods installed). The install is quite long - but end result is really nice. REMEMBER; You must active attribute tracking here: admin->catalog->product attributes-> when adding/editing an attribute, you must check the Track Stock? checkbox. Regards
