[8.54][TFS][LUA] What is wrong with this NPC? Console errors included.

Hiya there,

I use the following code in a NPC I made.

if msgcontains(msg, 'fix') then
    
	  if(getPlayerItemCount(cid, 1111) >= 1) then
			selfSay('Are you sure? I will give you 1 item in return.', cid)
			talkState[talkUser] = 1
		else
			selfSay('You do not have any items.', cid)
		end
	elseif(msgcontains(msg, 'yes') and talkState[talkUser] == 1) then
		if(getPlayerItemCount(cid, 1111) >= 1) then
			if(doPlayerTakeItem(cid, 1111, 1) == TRUE) then
				doPlayerGiveItem(cid, 2222, 1)
				selfSay('Here you are.', cid)
			end
		else
			selfSay('Sorry, you don\'t have the requested item.', cid)
		end
		talkState[talkUser] = 0
	elseif(msgcontains(msg, 'no') and isInArray({1}, talkState[talkUser]) == TRUE) then
		talkState[talkUser] = 0
		selfSay('Ok then.', cid)
	end

It asks for a single item, and if you say fix, yes, you trade the item for a other item. (2222). However, when I say yes, nothing happens.

Console error;

Any idea?

Thanks in advance.

It happens because talkUser is nil. Either change it to 'cid' or paste this line before your code:

local talkUser = NPCHANDLER_CONVBEHAVIOR == CONVERSATION_DEFAULT and 0 or cid

Thanks for your reply.
Pasting your code, I get this as a result saying fix, yes;

Then just replace every single instance of talkUser with cid?!
