What i am trying to do is use a "Token" to buy an item from the npc, everything works i just get an error , I'm not 100% sure why i am getting this error.... Can anyone help?

Server version is TFS 1.2 as seen in the title of this post. (Client is 10.98 if it even matters.)

(["item 1] = {buyId = 2457, costId = 6527, costCount = 10}, the error with ["item 1"] is not it.. i messed it up while editing the post.)


EDIT!

Ok, so i found the problems... First problem was getItemInfo was not working with 1.2 for some reason.... so i changed it to getItemName, now it works.

Second issue was with (npcTable[string.lower(msg)].costId).plural the .plural was not working at all, so i fixed this by simply deleting it, Now the script works good.. no more errors.
