Untradable items!

Hello there!
I coded the:
ChiPill(100)
ChiPill(200)
ChiPill(300)
ChiPill(400)

Items,
but i got a problem that it couldnt be sold or traded via Trading interface or Shopping .

That's so important to make it Tradable . sure u understand wut i mean, that players will have to collect and sell their chi pills for cps ..

i think it's in itemtype.dat

but i specifically dun know what should i edit.

thank yea.

Set the item monopoly to 0 both client and database..

It's Done, thank's the problem was in Items.txt/ItemType.txt
^_^
