Command not displaying total hours?

When *;hours * is ran, the value says 0 but I clearly have more than 0 hours. Help is appreciated, thanks!

local DatastoreService = game:GetService("DataStoreService")

local player = game.Players.LocalPlayer
local hoursValue= Instance.new("NumberValue", player)

player.Chatted:Connect(function(msg)
            if msg == ";hours" then 

                        wait(0.1)

                        game.StarterGui:SetCore('ChatMakeSystemMessage', {
                                                Text = "You have " .. hoursValue.Value .. " Total hours";
                            Color = Color3.fromRGB(76, 255, 0);
                            Font = Enum.Font.SourceSansLight;
                            TextSize = 20;
                        })  
        end

end)
