Its fixed, in the 'Currency' page.
Thanks for your reply, but I'm sorry I don't see a currency page in the "new trade" webpage. Under the "buying" section I only have tabs for TF2, DOTA 2 and Portal 2, and within the TF2 tab there is only buttons for heavy, spy, medic, pyro, soldier, scout, demoman, others, sniper, and engineer. I checked the "others" tab within TF2 and I didn't see anything for "any weapon".
Thanks for your help
