while true do
    wait(5)
    print "lol"
    normalTemperature()
    alarmMinor()
    alarmMajor()
end

And this is the error:

21:10:17.277 - Workspace.Meltdown Detector:79: attempt to call global 'normalTemperature' (a nil value)
21:10:17.277 - Stack Begin
21:10:17.277 - Script 'Workspace.Meltdown Detector', Line 79 
21:10:17.278 - Stack End
-- Also line 79 is "normalTemperature()"

I don't know what is wrong. Please help asap! :)

Can you give us the full script? It looks like either normalTemperature, alarmMinor, or alarmMajor is not defined. Merely 2122 — 10y

Merely is correct. Based on the positioning of your ends, the second function is only defined after the first is called, and the third only after the second! Also, there appears to be an extra 'end'.

This is very easy to see if you properly indent and un-indent your lines:

--snip

function alarmMinor()
    if currentTemp.Value >= 700 then
        --snip
        for i = 1, #firethree do
            --snip
            for i = 1, #mainframelights do
                --snip
            end
        end
    end

    function alarmMajor()
        if currentTemp.Value >= 1000 then
            --snip
            for i = 1, #emergencylightson do
                --snip
                for i = 1, #fireone do
                    --snip
                end
            end
        end


        function normalTemperature()
            if currentTemp.Value < 699 then
                --snip
                for i = 1, #fireone do
                    --snip
                    for i = 1, #mainframelightsthree do
                        ---snip
                    end
                end 
            end
        end
    end
end

while true do
    --snip
end

Ahh, I see where I went wrong :) Thank you. I shall give you the best answer because you gave me the full script. Sorry Merely! :p WelpNathan 307 — 10y

Merely was merely trying to point you in the general direction of the answer. Like I said, it isn't obvious until you fix the indentation. adark 5487 — 10y

That error occurs when you try to call a function that you haven't defined.

For example:

testFunction()

15:31:01.765 - testFunction():1: attempt to call global 'testFunction' (a nil value)

I am sure I defined it. I just edited my script to show it all. WelpNathan 307 — 10y
