How can i improve my barrierField in this local script?

IN the Barrier field section when i make the barrier i sometimes spawn outside of it. Also, sometimes the cooldown for Enabled doesnt work and i am able to make the barrier either an extra time, extra two times, or endlessly make them. I need to help to fix this. Also, plz give me suggestions on how i can make this barrier much much better and look professional.

Here is the script. Dont mind the barrier section. ONLY THE BARRIER FIELD SECTION!!!

local Tool = script.Parent
Player = game.Players.LocalPlayer
local mouse = Player:GetMouse()
char = Player.Character
hum = char.Humanoid 
root = char.HumanoidRootPart
local UIS = game:GetService("UserInputService")
local RemoteEvent = Tool.RemoteEvent
local Enabled = true

local en = true
Tool.Activated:connect(function()
if not en then return end
 en = false
wait(2)
en = true
end)


 local Debounce = false

UIS.InputBegan:Connect(function(Input)
if Input.KeyCode == Enum.KeyCode.Q then
	if Debounce == true then return end
	Debounce = true
	local Sound = Instance.new("Sound")
	Sound.SoundId = "rbxassetid://1146690806"
	Sound.PlaybackSpeed = 1
	Sound.MaxDistance = 100000
	Sound.Volume = 10
	Sound.Parent = char.HumanoidRootPart
	Sound:Play()
	RemoteEvent:FireServer(Debounce)
	wait(2)
	Debounce = false
end








end)




mouse.KeyDown:Connect(function(key)
if Enabled == false then return end
key = key:lower()
if key == "e" then
	Enabled = false
	local Sound = Instance.new("Sound")
	Sound.SoundId = "rbxassetid://2394905313"
	Sound.Volume = 10
	Sound.PlaybackSpeed = 1
	Sound.MaxDistance = 10000
	Sound.Parent = char.HumanoidRootPart
	Sound:Play()
	local BarrierField = Instance.new("Part")
	BarrierField.BrickColor = BrickColor.new("Lime green")
	BarrierField.Shape = "Ball"
	BarrierField.Material = "Neon"
	BarrierField.Anchored = true
	BarrierField.CanCollide = true
	BarrierField.Transparency = 0.5
	BarrierField.Size = Vector3.new(32,32,32)
	BarrierField.CFrame = char.HumanoidRootPart.CFrame
	BarrierField.Locked = true
	BarrierField.Parent = char
	
	wait(7)
BarrierField:Destroy()
	
end

wait(5)
Enabled = true

end)
