Thats ok I'm not to sure about lua syntax.

However I've spotted a spelling mistake in your code:

        OnLoad=function(self)
            self:RegsiterEvent'CHAT_MSG_CHANNEL_NOTICE'
        end,
        OnEvent=function(self)
            if event == "CHAT_MSG_CHANNEL_NOTICE" then
            if arg1 == "YOU_JOINED" and arg7 == 2 then
                Recount_MainWindow:Hide()
            elseif arg1 == "YOU_LEFT" and arg7 == 2 then
                Recount_MainWindow:Show()
                end
            end
        end,

should be:

        OnLoad=function(self)
            self:RegisterEvent'CHAT_MSG_CHANNEL_NOTICE'
        end,
        OnEvent=function(self)
            if event == "CHAT_MSG_CHANNEL_NOTICE" then
            if arg1 == "YOU_JOINED" and arg7 == 2 then
                Recount_MainWindow:Hide()
            elseif arg1 == "YOU_LEFT" and arg7 == 2 then
                Recount_MainWindow:Show()
                end
            end
        end,

See if that helps.
