How would i disable this gui after it is clicked?

I was wondering how to make a gui dissapear after it's clicked and when the character respawns it would reapear. Here is my script just to see if you coulda find something wrong. I tried game.StarterGui.Swordsmangiver.Disabled but it did not not work. if you could help me that would be greatly appreciated.

-- creating a screen gui
local screenGui = Instance.new("ScreenGui")
screenGui.Parent = script.Parent

--make a text button
local textButton = Instance.new ("TextButton")
textButton.Parent = screenGui
textButton.Position = UDim2.new(0,50,0,150)
textButton.Size = UDim2.new(0,140,0,60)
textButton.TextColor3 = BrickColor.White().Color
textButton.Style = 3
textButton.Text = "Swordsman"

--Bind function to button click
textButton.MouseButton1Down:connect(function()
p = game.Players.LocalPlayer
sword = game.ReplicatedStorage.ChristmasTreeSword:clone()--Weapon name
shield = game.ReplicatedStorage.Shield:clone()
if p.Backpack:FindFirstChild(sword.Name)~= nil then return end
if p.Backpack:FindFirstChild(shield.Name)~= nil then return end
p.Backpack:ClearAllChildren()
sword.Parent = p.Backpack
shield.Parent = p.Backpack
p.Character.Humanoid.WalkSpeed = 18
end)

Things to consider: This is a localscript inside the StarterGui. The script works and everything but i don't know how to disable after click and renable after death.
