Can somebody tells me what this error means?
Error: SAFshop\speedometer.lua:20 bad argument #1 to 'floor' (number expected, got nil)

Script:

Spoiler

local rx, ry = guiGetScreenSize ( )

function vehiclestatus ( )
	local theVehicle = getPedOccupiedVehicle ( localPlayer )
	if theVehicle and getPedOccupiedVehicleSeat (localPlayer) == 0 then
		local car = getPedOccupiedVehicle ( localPlayer )
		local currentFuel = tonumber(getElementData(car,"fuel"))
		local x, y, z = getElementPosition( localPlayer )
		local sx, sy, sz = getElementVelocity ( car )
		local kphSpeed = math.ceil( ( ( sx^2 + sy^2 + sz^2 ) ^ ( 0.5 ) ) * 161 )
		local mphSpeed = math.ceil( ( ( ( sx^2 + sy^2 + sz^2 ) ^ ( 0.5 ) ) * 161 ) / 1.61 )
		local health = getElementHealth ( car )
		local name = getVehicleName ( car )
		local currenthealth = math.floor( health/10 )
		-- dxDraw --

Error: SAFshop\speedometer.lua:20 bad argument  'math.floor' at argument 1 (number expected, got nil)

 

Now can you understand it?

Yes now i know what the error means
But still don't understand why it has no number.

This is a function of a other script (same resource):
 

Spoiler

function setFuel(player,seat,jacked,vehicle)
	if(getElementData(source,"fuel") == false) then
		fuel = math.random(70,100)
		setElementData(source,"fuel",tonumber(fuel))
	end
end
addEventHandler("onClientVehicleEnter",getRootElement(),setFuel)

It means you pass a nil value into the function math.floor as its first argument.

It means you haven’t set a value to currentFuel
