I am attempting to make a drug system to release on the MTA Community but there are some bugs which i cannot for the life of me find, here is the code;

function onGUIChange () 
    if drugDealer then 
        if getElementData(drugDealer, "DrugsDealer") then 
            MaxHeroin = (getElementData(drugDealer, "Heroin") or 0) + (getElementData(localPlayer, "Heroin") or 0) 
            MaxSteroids = (getElementData(drugDealer, "Steroids") or 0) + (getElementData(localPlayer, "Steroids") or 0) 
            MaxGod = (getElementData(drugDealer, "God") or 0) + (getElementData(localPlayer, "God") or 0) 
            MaxWeed = (getElementData(drugDealer, "Weed") or 0) + (getElementData(localPlayer, "Weed") or 0) 
            MaxSpeed = (getElementData(drugDealer, "Speed") or 0) + (getElementData(localPlayer, "Speed") or 0) 
            MaxCrack = (getElementData(drugDealer, "Crack") or 0) + (getElementData(localPlayer, "Crack") or 0) 
        else 
            outputChatBox("This Player is not selling drugs anymore, sorry", 255, 0, 0) 
            drugDealer = nil 
            guiSetVisible(window[2], false) 
            showCursor(false) 
        end 
    else 
        --Change this to the maximum drug amount that you can carry for each type of drug 
        MaxHeroin = 5000000 
        MaxSteroids = 5000000 
        MaxGod = 5000000

        MaxCrack = 5000000 
    end 
    local Text = guiGetText(source) 
    local Text = tonumber(Text) 
    if source == edit[1] then 
        local Amount = getElementData(localPlayer, "Heroin") or 0 
        if not Text then 
            guiSetText(source, "0") 
        elseif Text+Amount > MaxHeroin then 
            guiSetText(edit[1], MaxHeroin-Amount >= 0 and MaxHeroin-Amount or "0")

When i attempt to buy Heroin and Weed it just doesn't do anything, when i attempt to buy Crack AND Speed, it just says in the debug, "attempt to compare number with nil", and when i buy Steroids and God, it works as it triggers the server-side event (even tho it is not added yet, but works), thank you if you can help me

What line is this error on?

EDIT: It's line 90 in the code i posted, and the error occurs when i attempt to buy Speed AND Crack together

Edited the main post, sorry if i confused you, 226 is the bugged line WITH THE GUI, but this code doesn't have the GUI so, sorry

Can you tell me how you got the script, i don't remember selling it to you. Also releasing a script to the community that you didn't make is kind of rude.
