How to make it work?

Hello everyone, I have problem with button to tycoon. I created new button, but i added 2 parts and decal. Decal and second part won't remove/disappear. I tried to add in script lines, which should remove them, but don't work.

Here is long script: (It's from berezaa tycoon kit)

script.Parent:WaitForChild("Buttons")
for i,v in pairs(script.Parent.Buttons:GetChildren()) do
    if v:FindFirstChild("Head") then

        local object = script.Parent.Purchases:FindFirstChild(v.Object.Value)
        if object ~= nil then
            objects[object.Name] = object:Clone()
            object:Destroy()
        else
            print("Button: "..v.Name.." is missing its object and has been removed.")
            v.Head.CanCollide = false
            v.Head.Transparency = 1
            v.Head.Decal.Transparency = 1
            v.T.CanCollide = false
            v.T.Transparency = 1
        end

        if v:FindFirstChild("Dependency") then
            v.Head.CanCollide = false
            v.Head.Transparency = 1
            coroutine.resume(coroutine.create(function()    
                if script.Parent.PurchasedObjects:WaitForChild(v.Dependency.Value) then     
                    if v:FindFirstChild("RequiredGamepass") then
                        local tycoonOwner = script.Parent.Owner.Value
                        if tycoonOwner then
                            if game.GamePassService:PlayerHasPass(tycoonOwner,v.RequiredGamepass.Value) then
