MouseButton1Click LocalScript are not working and the Output doesnt show anything, why?

So I'm a new roblox developer and I made a script that for some reason won't work, can someone help me out?

script.Parent.MouseButton1Click:Connect(function(player)
    if game.Players.LocalPlayer.refill.Reff.Value == 0 then wait()
    game.Players.LocalPlayer.refill.Reff.Value = 1
end
end)

*both refill and Reff are somes strings that I made

I use it like this

--Say where the button is located
--(in my case player.PlayerGui.Guiscreen.frame.button
--so my script is in the Guiscreen)

local GoldButton, state = script.Parent.GiveFrame.GoldButton, false

GoldButton.MouseButton1Down:connect(function(player#(=game.Players.Player that clicked)#)

	--Make a Value so u dont need to repeat the game.blablabla-stuff.
	local PRV = player#(=game.Players.Player that clicked)#.refill.Reff

	if state == false then
		state = true
		if  PRV.Value ==  0 then 
			wait()
			PRV.Value = 1
		else
			PRV.Value = 0
		end
	else
		state = false
	end
end)

or when click on parts

-- The door 'BasePart'

local door = script.Parent

-- Asset ID of the image you want the to set the cursor to

local CursorId = "3190239131"

-- Create a ClickDetector

local ClickDetector = Instance.new("ClickDetector")

ClickDetector.Parent = door

ClickDetector.MaxActivationDistance = 15

ClickDetector.CursorIcon = "rbxassetid://"..CursorId


ClickDetector.MouseHoverEnter:Connect(function()

end)

ClickDetector.MouseHoverLeave:Connect(function()

end)

ClickDetector.MouseClick:Connect(function(player#(player  that clicked or part that they need to click on)#)

end)

ClickDetector.RightMouseClick:Connect(function(player)

end)

Del the #.....# parts they are just explaining
