How do I make a localscript that opens a GUI when you click on it's parent?[Solved]

I'm trying to make a part that you have to insert an answer into. I added a ScreenGUI to starterGUI, and added this localscript to open it when you click on the script's parent.

local function onMC(playerwhoclicked)
	playerwhoclicked.PlayerGui.submit.TextBox.Visible = true
	playerwhoclicked.PlayerGui.submit.TextButton.Visible = true
end

script.Parent.ClickDetector.MouseClick:connect(onMC)

The problem is, the script doesn't open anything. Also, none of the errors in console link to the script when clicked on. Keep in mind, I don't know anything about localscripts other than that they are scripts that are local.

--Place your gui in server storage
local name="ScreenGui" -- Place the name of your Gui here

function onclick(plr)
local x = game.ServerStorage.name:Clone()
x.parent = plr.PlayerGui --if your button is derectly in a screen gui then it whould be better if you type x.parent = script.Parent.Parent.Parent
end

script.Parent.ClickDetector.MouseButton1Click:Connect(onclick)

There can be mistakes in this script, if you find mistake please fix it, hope script help. And place it in normal script not in local script.
