Here is the script

Code:

    if (parameters.confirm ~= true) and (parameters.decline ~= true) then

How do I get rid of the "getItemNameById" since I am using OTServ r.6052, I do not have this function but the rest of the script seems like it should work fine, but this little part makes the whole script not work. So how do I just get rid of that tiny instance? And yes, I have tried a few things and they have not worked.

go to data/npc/scripts/lib/npc system
Open keywordhandler and changed for this
LUA: 
-- Advanced NPC System (Created by Jiddo),
-- Modified by Talaturen.

if(KeywordHandler == nil) then
	BEHAVIOR_SIMPLE = 1 -- Does not support nested keywords. If you choose this setting you must use a variable such as 'talkState' to keep track of how to handle keywords.
	BEHAVIOR_NORMAL = 2 -- Default behvaior. If a sub-keyword is not found, then the root is searched, not the parent hierarchy,
	BEHAVIOR_NORMAL_EXTENDED = 3 -- Same as BEHAVIOR_NORMAL but it also searches through the last node's parent.
	BEHAVIOR_COMPLEX = 4 -- Extended behavior. It a sub-keyword is not found, then the entire keyword hierarchy is searched upwards until root is reached.

	-- BEHAVIOR_NORMAL_EXTENDED is recommended as it (probably) mimics the behavior of real Tibia's NPCs the most.
	--		However, you are strongly recommended to test some (or all) other settings as well as it might suit you better.
	--		Also note that not much difference can be seen with the different settings unless you have a npc with a quite heavy
	--		nestled keyword hierarchy.
	-- Note: BEHAVIOR_SIMPLE should not be used unless you have any special reason to do so as it forces you to keep track of talkStates etc.
	--		This was pretty much the method used in the 2.0x versions of this system. It is here mainly for compability issues.

Ok, now I'm getting this error

Sorry about all this trouble, I'm just not good with npc's and I dont want to change npc systems and have to redo the 15 or so other npcs I've already made that have quests in them and sell/buy stuff.
