How do I fix this error that I get when I test the game?

When I test the game, this appears in the output:

15:25:56.297 - Players.MinecraftButterfly87.PlayerGui.LocalScript:14: Expected ')' (to close '(' at line 8), got <eof>

This is what's in the scipt:

local debounce = false

local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
 
if debounce == false then
   debounce = true --Now your code will not run, because debounce is not false.
   	mouse.KeyDown:connect(function(key)
	    if key == "e" then
 	      print("Pressed e")
    wait(5)
    debounce = false --Now your code will run again.
	end)
end

To start, insert a LocalScript in StarterGui.

Inside of the LocalScript type this:

local keydown = false

game:GetService("UserInputService").InputBegan:Connect(function(key, GPE)
	keydown = true
	if key.KeyCode == Enum.KeyCode.E and not GPE then
		print("Pressed e")
	end
end)

When you press e, the game will print "Pressed e".

If this did work, please mark this as the solution. If you were looking for something else, please comment on this answer what you specifically want and I'll try to make it :)) .
