Custom Character Gui Local Script Problem?

I'm trying to make a custom character gui and I've been watching different tutorials as reference for what I want to do with it and how I want it edited. But, I've come to a pause because I can't seem to figure out why the Value's aren't changing and the buttons within the gui aren't working :/ All suggestions and ideas are welcome. Thanks!

This is what my Local Script looks like rn:

local player = script.Parent.Parent.Parent.Parent.Parent
local Hat = player:WaitForChild("Hat")
local HatFolder = game:GetService("ReplicatedStorage"):WaitForChild('Hats')

local Hats = {}

local hat1 = script.Parent:WaitForChild('Hat1Button')
local hat2 = script.Parent:WaitForChild('Hat2Button')
local hat3 = script.Parent:WaitForChild('Hat3Button')

local toggle = false


function Update()
    script.Parent:WaitForChild('HatName').Text = Hat.Value
    wait(0.01)
end


hat1.MouseButton1Down:connect(function()
    if toggle == false then
        script.Parent.HatName.Text = "Hat1"
        wait(0.01)
        script.Parent.Wear1.Visible = true
        script.Parent.Wear2.Visible = false
        script.Parent.Wear3.Visible = false
        Update()
    end
end)


hat2.MouseButton1Down:connect(function()
    if toggle == false then
        script.Parent.HatName.Text = "Hat2"
        wait(0.01)
        script.Parent.Wear1.Visible = false
        script.Parent.Wear2.Visible = true
        script.Parent.Wear3.Visible = false
        Update()
    end
end)


hat3.MouseButton1Down:connect(function()
    if toggle == false then
        script.Parent.HatName.Text = "Hat3"
        wait(0.01)
        script.Parent.Wear1.Visible = false
        script.Parent.Wear2.Visible = false
        script.Parent.Wear3.Visible = true
        Update()
    end
end)

repeat wait() until game.Workspace.CurrentCamera
local camera = game.Workspace.CurrentCamera

local character = game:GetService('ReplicatedStorage'):WaitForChild('CustomCharacter'):Clone()

local player = game.Players.LocalPlayer

local Hat = player:WaitForChild("Hat")
local Shirt = player:WaitForChild("Shirt")
local Pants = player:WaitForChild("Pants")

character.Parent = camera



function Update()
    for i,v in pairs(character:GetChildren()) do
        if v:IsA("Hat") or v:IsA("Pants") or v:IsA("Shirt") then
            v:remove()
        end
    end

    Hat.Value:Clone().Parent = character
    Shirt.Value:Clone().Parent = character
    Pants.Value:Clone().Parent = character

end


Hat.Changed:connect(function()
    Update()
end)

Shirt.Changed:connect(function()
    Update()
end)

Pants.Changed:connect(function()
    Update()
end)
