	local talkUser = NPCHANDLER_CONVBEHAVIOR == CONVERSATION_DEFAULT and 0 or cid

	local needItems = {id = {2176}, count = {50}}
	local tradeItems = {id = {2498}, count = {1}}
	
	if(msgcontains(msg, 'exchange') or msgcontains(msg, 'change')) then
		selfSay('Do you want to change '.. needItems.count[1] ..' '.. getItemNameById(needItems.id[1]) ..'s for '.. tradeItems.count[1] ..' '.. getItemNameById(tradeItems.id[1]) ..'?', cid)
		talkState[talkUser] = 1

npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)

i can put other items?

 

[Mooosie]

Yea, but you can only change 1 item for 1 item. Just write the item id. But you cannot do more items. I have'nt done that in the script.
But does it work?
