Why isnt this local script working as expected? Events, and Input Service

So the script works but when Click my mouse or do anything it just turns the frame's Visibility to false i used print instead of visibility but every time i hit E it prints it 20 times please help! :

local PrincipleNPC = workspace.NPCS.PrincipleNPC
local Detector = workspace.PlayerDetectors.PrincipleDetector

local eToTalk = script.Parent.eToTalk
local Touching = false

local UIS = game:GetService("UserInputService")

Detector.Touched:Connect(function()
	eToTalk:TweenPosition(UDim2.new(0.262, 0 ,0.771, 0),"Out","Quart",0.2)
	Touching = true
	UIS.InputBegan:Connect(function(input)
		if Touching == true and input.KeyCode == Enum.KeyCode.E  then
			script.Parent.Frame.Visible = true
		else
			Touching = false
			return
		end
	end)
end)

Detector.TouchEnded:Connect(function()
	eToTalk:TweenPosition(UDim2.new(0.262, 0,1, 0),"In","Quart",0.2)
	UIS.InputBegan:Connect(function()
		if Touching == false then
			script.Parent.Frame.Visible = false
			Touching = false
		end
	end)
end)
