how do i add an LM to an already being sold item in my magic box?

[Crikett]

I have allredy added 9 items to the market place, but.... I forgot to include my LM, how do I add that after the fact? and do I have to start that product all over again? thanks

You still have the boxed items in your inventory, so add the LM to them.  Then open your Magic Box and remove the ones that are there and replace them with the newly-modified ones.  So long as you don't change the names of the items in any way, the Marketplace software will continue to look for items with those names in your Magic Box and will just pick up the new ones instead of what was there before.
