Tycoons - Invisible buttons?

As I've seen in many Tycoon games, many tycoon creators have actually managed to make a tycoon kit that has hidden buttons that appear after you buy something, but they never release it to the public! I've been trying to make a tycoon with that for a long time and have had to success at all. I've tried putting the button in the model that the previous button generates and edited the variables a bit. It would error and say the model is nil. I've tried making the button transparent and then do it...but nothing would happen. Not even any output! So I tried the first idea again and edited the wait time and it did the same as the second...? Here's my Tycoon button:

--lightpower26
--Some of these variables just make it easier for me to create my tycoon.
main = script.Parent.Parent
owner = main.Owner
button = script.Parent
name = "Walls"
price = 100
model = main:FindFirstChild("Walls")
normalname = "Purchase "..name.." for $"..price
text = button.BillboardGui.TextLabel
text.Text = normalname
backup = model:Clone()
Debounce = false
wait(1)
model:Destroy()

button.Click.MouseHoverEnter:connect(function(plr)
    if plr.Name ~= owner.Value then return end
    if plr.leaderstats.Cash.Value >= price then
        text.TextColor3 = Color3.new(0, 1, 0)
        text.TextStrokeColor3 = Color3.new(1, 1, 1)
        text.Text = "Click to "..normalname
    elseif plr.leaderstats.Cash.Value < price then
        text.Text = "You need "..(price - plr.leaderstats.Cash.Value).." more Cash to purchase "..name.."!"
        text.TextColor3 = Color3.new(1, 0, 0)
        text.TextStrokeColor3 = Color3.new(1, 1, 1)
    end
end)

button.Click.MouseHoverLeave:connect(function(plr)
    if plr.Name ~= owner.Value then return end
    text.Text = normalname
    text.TextColor3 = Color3.new(1, 1, 1)
    text.TextStrokeColor3 = Color3.new(0, 0, 0)
end)

button.Click.MouseClick:connect(function(plr)
    if button.Transparency >= 0 then
        if not Debounce then
            if plr.Name ~= owner.Value then 
                Debounce = true
                if owner.Value ~= "" then
                    text.Text = owner.Value.." owns this mine! Not you!"
                elseif owner.Value == "" then
                    text.Text = "No one owns this mine!"
                end
                text.TextColor3 = Color3.new(1, 0, 0)
                text.TextStrokeColor3 = Color3.new(1, 1, 1)
                delay(0.5, function()
                    text.Text = normalname
                    text.TextColor3 = Color3.new(1, 1, 1)
                    text.TextStrokeColor3 = Color3.new(0, 0, 0)
                end)
                wait(0.5)
                Debounce = false
                return
            end
            if plr.leaderstats.Cash.Value < price then
                Debounce = true 
                text.Text = "You need "..(price - plr.leaderstats.Cash.Value).." more Cash to purchase "..name.."!"
                text.TextColor3 = Color3.new(1, 0, 0)
                text.TextStrokeColor3 = Color3.new(1, 1, 1)
                delay(0.5, function()
                    text.Text = normalname

                    text.TextStrokeColor3 = Color3.new(0, 0, 0)
                end)
                wait(0.5)
                Debounce = false
                return
            end
            Debounce = true
            plr.leaderstats.Cash.Value = plr.leaderstats.Cash.Value-price
            text.Text = "Purchasing..."
            text.TextColor3 = Color3.new(0, 0, 1)
            text.TextStrokeColor3 = Color3.new(1, 1, 1)
            model = backup:Clone()
            model.Parent = main
            for i = 0, 1, 0.05 do
                text.TextTransparency = i
                text.TextStrokeTransparency = i
                button.Transparency = i
                wait()
            end

            game.ReplicatedStorage.ChatEvent:FireClient(plr, plr, "You have succesfully purchased "..normalname.."!")
            wait(0.1)
            Debounce = false
            button:Destroy()
        end
    end
end)

Please help me! I've looked all over the internet and roblox forums (which no one looks at my posts...) for an answer!
