Why aren't GUIs moving with .Touched and Tweens?

I went to go test my game in the Test tab, and i come to find that a script that tweens parts doesn't work, and a script that tweens a GUI onto your screen doesn't work. Why? I've tried everything i know to try to fix it but nothing seems to work...

here is the script that tweens the GUI onto your screen.

script.Parent.Touched:connect(function(hit)
	if hit.Parent:FindFirstChild("Humanoid") ~= nil then
	local gui   = game.Players[hit.Parent.Name]:FindFirstChild("PlayerGui").ShopGui.CornerCafe
	gui:TweenPosition(UDim2.new(.1, 0,0.2, 0),1,0,.3)
	end
end)

script.Parent.TouchEnded:connect(function(hit)
	if hit.Parent:FindFirstChild("Humanoid") ~= nil then
	local gui   = game.Players[hit.Parent.Name]:FindFirstChild("PlayerGui").ShopGui.CornerCafe
	gui:TweenPosition(UDim2.new(-0.3, 0,0.2, 0),1,0,.3)
	end
end)

Here is the script that tweens the 2 Parts

local TweenService = game:GetService("TweenService")

 check        = false
local sensor       = script.Parent
local door1        = script.Parent.Parent.Floor_1.OutsideDoor.DoorLeft
local door2        = script.Parent.Parent.Floor_1.OutsideDoor.DoorRight

local tweeninformation    = TweenInfo.new(
	0.5,
	Enum.EasingStyle.Linear,
	Enum.EasingDirection.Out,
	0,
	false,
	0)

local door1open   = {CFrame = CFrame.new(210.675, 6.175, -577.876)}
local door1close  = {CFrame = CFrame.new(216.825, 6.175, -577.876)}
local door2open   = {CFrame = CFrame.new(229.6, 6.175, -577.876)}
local door2close  = {CFrame = CFrame.new(223.25, 6.175, -577.876)}

local tween1open  = TweenService:Create(door1,tweeninformation,door1open)
local tween1close = TweenService:Create(door1,tweeninformation,door1close)
local tween2open  = TweenService:Create(door2,tweeninformation,door2open)
local tween2close = TweenService:Create(door2,tweeninformation,door2close)

sensor.Touched:Connect(function(hit)
	if hit.Parent:FindFirstChild("Humanoid") then
	print"touched"
	if check == false then
			
			check = true
		if 	game.Players[hit.Parent.Name].PlayerGui.NPCChat.NPC_Dialog.Visible == true then
			local reason = "Chat ended because you walked away"
			game:GetService("ServerScriptService").NoticeGUIEvent.Reason.Value = reason
			game:GetService("ReplicatedStorage").RemoteEvents.NoticeGUI:FireServer(hit.Parent.Name)
		end
		game.Players[hit.Parent.Name].PlayerGui.NPCChat.NPC_Dialog.Visible = false
		game.Players[hit.Parent.Name].PlayerGui.NPCChat.NPC_Dialog.Frame.Accept.Text   = "Accept"
		game.Players[hit.Parent.Name].PlayerGui.NPCChat.NPC_Dialog.Frame.Decline.Text  = "Decline"
		game.Players[hit.Parent.Name].PlayerGui.NPCChat.NPC_Dialog.Frame.Desc1.Text    = " "
		game.Players[hit.Parent.Name].PlayerGui.NPCChat.NPC_Dialog.Frame.NpcName.Text  = "Name"
		
		
		tween1open:Play()
		tween2open:Play()			
			
	wait(2)
			
			check = false	
			
		tween1close:Play()
		tween2close:Play()
		
		game:GetService("ServerScriptService").NoticeGUIEvent.Reason.Value = " "
			
		end	
	end
end)

if anyone is able to help me and tell me why they aren't working it would mean a ton to me.

Are you sure it’s because of check = true? Try moving check = true to somewhere else maybe that will fix your problem.

 if check == false then

            check = true. <===========
        if  game.Players[hit.Parent.Name].PlayerGui.NPCChat.NPC_Dialog.Visible == true then
            local reason = "Chat ended because you walked away"
            game:GetService("ServerScriptService").NoticeGUIEvent.Reason.Value = reason
            game:GetService("ReplicatedStorage").RemoteEvents.NoticeGUI:FireServer(hit.Parent.Name)
        end
        game.Players[hit.Parent.Name].PlayerGui.NPCChat.NPC_Dialog.Visible = false
        game.Players[hit.Parent.Name].PlayerGui.NPCChat.NPC_Dialog.Frame.Accept.Text   = "Accept"
        game.Players[hit.Parent.Name].PlayerGui.NPCChat.NPC_Dialog.Frame.Decline.Text  = "Decline"
        game.Players[hit.Parent.Name].PlayerGui.NPCChat.NPC_Dialog.Frame.Desc1.Text    = " "
        game.Players[hit.Parent.Name].PlayerGui.NPCChat.NPC_Dialog.Frame.NpcName.Text  = "Name"


        tween1open:Play()
        tween2open:Play()           

    wait(2)

            check = false   

        tween1close:Play()
        tween2close:Play()

        game:GetService("ServerScriptService").NoticeGUIEvent.Reason.Value = " "

        end 
    end
end)
