how do i post to the trade board

I apologize if this question seems stupid. I purchased a couple premium tabs and put items inside. I noticed there is an option to set a note. However, when I do nothing seems to happen. I check the trade board and the items I set notes to are not there. Am I doing something wrong? Is there more to selling an item on the board than that? Any help is valued. I appreciate it.

You need to set the premium stash tab to public. You use the note to adjust the amount you're asking for
