I had this problem also. I could not figure out how my items were to be added under a perticular catagory. If I am not mistaked it depends on the "key words" that you enter into the catagories. If the "description" of your "item" has any of these key words in it it will automaticly go under that catagory. Please don't hold me to this because it's just a guess. I can't find any help from Auctiva on this subject either.
