error in script Awayer v 4.lua

[Oz]

hi all, have error in this script, can some help me?

[23:27] Syntax ...s\Bom\Desktop\0.3.5.1.lua5.0.2\scripts\!alarmbot.lua:253: attempt to perform arithmetic on a nil value

--- --- --- Awayer v 4 --- ---

--lua 5 version

--By jiten and Dessamator 

-- 1) Converted to lua 5

-- 2) Some bug fixes  

-- 3) enabled it for normal users (not recommended)

-- 4) added allowuser check

-- 5) removed myinfo arrival (not needed)

--- --- --- --- --- --- ---

---  Awayer v3 --- idea by QuitckThinker

--- by Herodes

--- This bot has been writen offline and based on no other script

--- Although the initial idea for the AwayBot is from tezlo's RetroBot...

--- This diplays a prefix for those operators and above that are away

--- It also places the Away message in the users description ...

--- --- --- This script works only for Operators (as intended) --- --- ---

--- !away <reason>   --- <reason> is optional

--- !back

--- !awaylist

--- feel free to develop this further ...  

--- --- v 2 --- ---

--- currently has a problem with the following path ..

--- 1) <user> !away

--- 2) user reconnnects 

--- 3) <user> !back 

--- this produces a lot of shity names in the list ... dunno y ...:(

--- --- v 3 --- ---

--- fixed v2 problem but has abother one ...

--- following path ..

--- 1) <user> !away

--- 2) <user> <chatmsg> or <user> !back

--- 3) user disconnects ...

--- 4) user receives nickname reserved message (???)

--- --- all other scenarios I have tested and work fine ...

To start with, you named ur script alarmbot and its got awayer's script inside. You've got an interesting way to name scripts.Ill assume you pasted the wrong script as im quite sure there is no arithmetic performed in the script you currently pasted.

[[ vAiBhAv?]]

hey dude, i had the same problem.. i switched over to a different script..
use this.. its good

--[[
Away 1.0 LUA 5.1
From LawMaker.
Sends away message.
No tag and other things like this.
You can see others' away messages w/o PMing them if you want.
Enjoy.
