Really need help with this in the G.E.C.K.

I have a sneaking suspicion that this wiki article titled 'http://geck.gamesas.com/index.php/Adding_items_to_vendors' might help you in your quest to add items to vendors.

(This isn't really the right sub-forum for this, by the way.)


Edit: And I said that before this was moved to the right sub-forum, for the record.
