ClickDetector script not working/code not running for some reason?

I have no idea why, but for some reason, I have made a click detector script and it is not running the code. here is the code:

print("Hello world!")
script.parent.MouseClick:Connect(function()
	print"hi"
	game.LocalPlayer.PlayerGui.Frame.Visible = true
end)
workspace.buttonthing.ClickDetector.Parent.Mouse:Connect(onMouseClick)

Line 2 has a typo, it should be script.Parent

I would also remove line 6

script.Parent.MouseClick:Connect(function()
    print("hi")
    game.LocalPlayer.PlayerGui.Frame.Visible = true
end)

Hello.

I've found a few errors in your script, So I decided to help you,

1. The Keyword: "Parent", Must start with Capitalized P (Line 2)

2. You forgot to add the () Symbols after Print Keyword, Similar with Line 1. (Line 3)

3. You got the "Connect" 2 Times, Just Erase the last line.

• If I got something wrong, Please tell me what is the wrong because it's important.

Here's the Script:

print("Hello world!")
script.Parent.MouseClick:Connect(function()
    print("hi")
    game.LocalPlayer.PlayerGui.Frame.Visible = true
       end
end)

It may have an Error, Because it doesn't detect if it's visible or not.

Or maybe I got it wrong...

So...

If you want the Close and Open Script, Which will work, I brought you one.

print("Hello world!")
script.Parent.MouseClick:Connect(function()
    print("hi")
     if game.StarterGUI.ScreenGUI.Frame.Visible == false then
     game.StarterGUI.ScreenGUI.Frame.Visible = true
   else
     game.StarterGUI.ScreenGUI.Frame.Visible = false
       end
end)

None of this works. Here is my new code:

print("Hello world!")
script.Parent.MouseClick:Connect(function()
	print("hi")
	game.LocalPlayer.StarterGui.ScreenGUI.Frame2.Visible = true
end)
