Broken "for" loops

[mueller_minki]

Could you post the code around the for loop?

Warning: this code is a mess. Im planning on making a /fill command and it has to run setBlock for every block inside an area the player provides using a command. For testing, i made the area 10 blocks on the x axis. If that would have worked, I would have run x, increment z by one, x, increment z, and so on until it has to increment y and then loop again.
Here it goes but be warned: It may cause eye cancer because im really bad at lua (this is the second time i made something in lua)

Code:

PLUGIN = nil

function Initialize(Plugin)
    Plugin:SetName("VanillaFill")
    Plugin:SetVersion(1)

    -- Hooks

    PLUGIN = Plugin -- NOTE: only needed if you want OnDisable() to use GetName() or something like that

    -- Command Bindings
    cPluginManager.BindCommand("/setblock", "vanillafill.setblock", setblock, " ~ Changes a block at X Y Z.");
    cPluginManager.BindCommand("/fill", "vanillafill.fill", fill, " ~ Fills an area from X Y Z to X2 Y2 Z2.");

    LOG("Initialised " .. Plugin:GetName() .. " v." .. Plugin:GetVersion())
    return true
end

function OnDisable()
    LOG(PLUGIN:GetName() .. " is shutting down...")
end
