[Eighty Swords]

I never set up a bag on razor to sell agent, i normally set an especific item, so it will sell only the item =x

Well you still have to set the hot bag, right? You probably set it to your backpack (by targeting it on your paperdoll). I suggest not to set it to your backpack because some newer versions of Razor will sell everything in your backpack that can be sold, not just the items on the sell list. This is why I suggested setting the hot bag to a bag in your backpack and running an organizer agent to move the bandannas to this bag when you say "<vendor name> sell". I hope that cleared things up for you
