I randomly get this Error in my database
Code: 
[26/06/2012 13:56:48] [Error - Npc interface]

Is there any way how to fix it? Because it keeps spamming. Also, here's my Greeter.lua:
Code: 
local focus = 0

end


function onCreatureTurn(creature)

Thanks :D I'll try it out for a bit and see if it doesn't do it again :D
~Edit: It worked! :D Except there was one little error that I found but I changed it :D It was just "CreatureGetName" I had to change to "Getcreaturename" and then it worked :D Thanks I gave you Rep!


Also I got another error : /
Whenever I open the book with writing in it that has the id of 1964, it gives me this error:
Code:

Here's my rwitems script:
Code: 
function onUse(cid, item, frompos, item2, topos)
   	rw = getItemRWInfo(item.uid)
   	if rw and 1 then
   		if rw and 2 then
   			doShowTextWindow(item.uid,100,1)
   		else
   			doShowTextWindow(item.uid,100,1)
   		end
   	else
   		if item.itemid == 2598 then
   			doShowTextWindow(item.uid,0,0)
   		end
   	end
   
   	return 1
    
   end

PHP: 
function onUse(cid, item, frompos, item2, topos)
   	rw = getItemRWInfo(item.uid)
   	if rw and 1 then
   		if rw and 2 then
   			doShowTextDialog(cid, 2598, text)
   		else
   			doShowTextDialog(cid, 2598, text)
   		end
   	else
   		if item.itemid == 2598 then
   			doShowTextDialog(cid, 2598, text)
   		end
   	end
   
   	return TRUE
    
   end
