Pressing E not making Gui visible but no errors?

I'm making an ATM machine for a roleplay game I'm working on. I made an "E to interact" and it worked with print so I replaced it with making the ATM Gui visible. It didn't work and there wasn't errors. I tried debugging and it came out positive. My code is a LocalScript:

local HumanoidRootPart = game.Players.LocalPlayer.Character:WaitForChild("HumanoidRootPart")
local UIS = game:GetService("UserInputService")
local Atm = game.Workspace.Atm

UIS.InputBegan:Connect(function(keyCode)
	if keyCode.keyCode == Enum.KeyCode.E then
		if (Atm.Position - HumanoidRootPart.Position).magnitude <10 then
			game.StarterGui.ScreenGui.FinnianATM.Visible = true
			print("Worked")
		end
	end
end)

if keyCode.keyCode == Enum.KeyCode.E then

to

if keyCode.keyCode == Enum.KeyCode.e then

probably

local UIS = game:GetService("UserInputService")
local ATMHitBox = game:GetService("Workspace"):FindFirstChild("ATM").HitBox
local Character = game.Players.LocalPlayer.Character or game.Players.LocalPlayer.CharacterAdded:Wait()

wait(0.25) --Wait For The Character To FULLY Load In

local HRP = Character:FindFirstChild("HumanoidRootPart")

UIS.InputBegan:Connect(function(key)
	if key.KeyCode == Enum.KeyCode.E then
		if (ATMHitBox.Position - HRP.Position).Magnitude < 10 then
			--Whatever You Want To Happen
			print("Works")
		end
	end
end)

This Also Works As Well
