my modulescript is a fail, can someone tell me what is wrong?

here is my ModuleScript:

game.Players.PlayerAdded:connect(function(player)-- this is just so I can declare the player
	plr = player.Name
end)
function waitforit(object)
	game.Workspace:WaitForChild(object)
end

function message(parent ,text, staytime)
	msg = Instance.new("Message")
	msg.Parent = parent
	msg.Text = text
	if staytime > 0 then
		wait(staytime)
		msg:destroy()
	end
end

function hint(text, staytime)
 playergui = game.Players.plr.PlayerGui
gui = Instance.new("ScreenGui")
gui.Parent = playergui
gui1 = Instance.new("TextLabel")
gui1.Text = text
gui1.Size.X = 1000
gui1.Size.Y = 50
if staytime > 0 then
	wait(staytime)
	gui1:destoy()
	gui:destoy()
end
end

now I want to be able to call a function like this:simplemodule.message("game.Workspace", "hello", 30) also none of these work can someone tell me what I did wrong?

What happened was you didn't return a table. Tables are required to add functions like simplemodule.message()

local tbl = {}
game.Players.PlayerAdded:connect(function(player)-- this is just so I can declare the player
    plr = player.Name
end)
-- You can also use function tbl:waitforit(object) so it can be a real method.
function tbl.waitforit(object)
    game.Workspace:WaitForChild(object)
end

function tbl.message(parent ,text, staytime)
    msg = Instance.new("Message")
    msg.Parent = parent
    msg.Text = text
    if staytime > 0 then
        wait(staytime)
        msg:destroy()
    end
end

function tbl.hint(text, staytime)
 playergui = game.Players.plr.PlayerGui
gui = Instance.new("ScreenGui")
gui.Parent = playergui
gui1 = Instance.new("TextLabel")
gui1.Text = text
gui1.Size.X = 1000
gui1.Size.Y = 50
if staytime > 0 then
    wait(staytime)
    gui1:destoy()
    gui:destoy()
end
end

return tbl

If I helped accept me as an answer and vote me up. Thank you! Also, sorry if any of this info is wrong. Its probably because I'm tired. D:

Game.Players.PlayerAdded:connect(function(player)
plr = Game.Players.LocalPlayer
end)

function waitforit(object)
game.Workspace:WaitForChild("	Object")
end

function hint(Parent, text,  StayTime)
msg = instance.new("Message")
msg.Parent = game.Workspace -- beacuse workspace is where everything goes.
msg.Text = "Wat is your text here"
if staytime > 0 then
wait() --  put seconds
msg:Destroy() -- beacuse msg was on Every Line.
   end
end


function hint(text, StayTime)

gui = instance.new("ScreenGUI")
gui.Parent = Game.StarterGUI -- you forgot the frame.
Frame = Instance.new("Frame")
TextLabel = Instance.new("TextLabel")
gui.Text = "" -- put your text between the ""
gui.Size.X = 1000
gui.Size.Y = 50

if staytime > 0 then
wait() -- put seconds between () like the code UnTop
Frame:Destroy()
TextLabel:Destroy()
gui:Destroy()

end
end
-- np. also Local Script.
