Why is this KeyDown function not working? [closed]

( Note : <http://wiki.roblox.com/index.php?title=Taking_keyboard_input >)

local debounce = false
local plyr = game.Players.LocalPlayer
local mouse = plyr:GetMouse()

mouse.KeyDown:connect(function(key)
            if debounce == false and key == 'r' then -- Works just fine
                debounce = true
                    plyr:LoadCharacter()
                     delay(3,function()
                    debounce = false
                end)
                elseif key == 'q' and debounce==false then  -- There is no 63 byte
              game.Lighting.HELP:Clone().Parent = plyr.PlayerGui
            delay(3,function()
                debounce = true
        end)
    end
end)

Try using this code as the first line.

wait(.5)

This usually fixes things for local scripts not always working. Due to local scripts loading faster than some player aspects this usually helps with letting them load first. If this doesn't work try adding a:

print(key)

, inside of the mouse.KeyDown:connect(function(key), as the next line in it. Here is the code that I think may work.

wait(.5)

local debounce = false
local plyr = game.Players.LocalPlayer
local mouse = plyr:GetMouse()

mouse.KeyDown:connect(function(key)
        print(key)
            if not debounce then
                debounce = true
                if string.lower(key) == "r" then
            plyr:LoadCharacter()
            wait(3)
            debounce = false
                elseif key:byte() == 63 then
                    game.Lighting.HELP:Clone().Parent = plyr.PlayerGui
                    wait(3)
                    debounce = false
        end
    end
end)
