Please do not try to sell items that are not in your account. Breaks rule:
C) Do not attempt to sell, or pay with items or Toricredits that are not in the inventory of the account that is posting. No; "It's in a bank account". This also covers the sale of items currently in the market.
I am going to close this thread as of now, but feel free to reopen it once it's on your account, or you can open a thread with the other account.
Thanks.
