Sorry for keeping posting things like this

I've been working on tradeskill "recipes" and so far have done Smithing and Jewellery.
I've added the data to the DB, with the correct skill IDs (jewellery=68, etc) and checked it out with EQEmuAdmin,
however when in the game it doesn't seem to work; I summon a jeweller's kit, a gem, and a metal bar, put them in the
kit and click combine, but get the message "You cannot combine these items in this container type!"
Do you need to add the container to the list of ingredients? Or is this feature bugged in 0.3.1?
