[HELP] Arithmetics issue

[AlexMiller]

Hi there. I'm ahving some problems with my payday script. It gets the cost of the car a player has and divides it for 1000 to get the tax you have to pay for owning it. The problem is that when i try to perform this arithmetic:

local tax2 = itscost /1000

I get this error:

attempt to perform arithmetic on global 'tax2'

I have already checked if itscost is true by using some outputchatbox and printing it. It shows the car cost correctly. Thanks for helping!

You are defining a local variable, and then using it outside its scope.

Or maybe, I misunderstood the error. Also try

tonumber(itscost)

I'm using it locally, in the same script, in the same function.

Um, can you paste greater portion of code?

Error says about arithmetic on tax2 but in this code you are performing arithmetic on itscost

Alright. That 2 ouputchatboxs were written to check if the variables were wroking fine.

function PayDay(plr, givepay)
 
local reincome = 200
local account = getPlayerAccount (plr)
local findcar = tonumber(getAccountData (account, "car"))
if findcar ~= 481 then
local itscost = tonumber(getAccountData (account, "carcost"))
outputChatBox("cost is " ..itscost)
outputChatBox("car is " ..findcar)
 
local tax2 = itscost/1000
else
local tax2 = "0"
end
 
local whatisgiven = reincome - tax2
 
local playerList = getElementsByType("player")
for key,val in ipairs(playersList) do
givePlayerMoney(val, whatisgiven)
 
end

Can anyone help me out with this?

If creates scope, and tax2 is local to this if. Remove local keyword and this will work. Tested.

@down: No problem
