I have a BoolValue, and it's value is very annoying to change... Anyone can help with this?

game.Players.PlayerAdded:Connect(function(plr)
	
	local leaderstats= Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = plr
	local cash = Instance.new("IntValue")
	cash.Name = "Dollars"
	cash.Value = 122000
	cash.Parent = leaderstats
	game.Players.LocalPlayer.PlayerGui:WaitForChild("Camaro", 10).Camaro.Purchased.Value = false
end)

game.ReplicatedStorage:WaitForChild("CheckPrice").OnServerInvoke = function(player, NameOfCar)
	return game.ServerStorage.Cars:FindFirstChild(NameOfCar).Price.Value
end

This script is in ServerScriptService, and someone suggested that the value should be set from here as it automatically runs. A GUI is also set in a 'phone' which sees whether a value is true or false, True = car spawner is there False = car spawner isn't there

local gui = game.Players.LocalPlayer.PlayerGui:WaitForChild("Camaro", 10).Camaro.Purchased -- add a waitforchild
local chevy = script.Parent.Parent.Chevy
script.Parent.MouseButton1Click:connect(function()
    wait(0.3)
    if gui.Value == true then
        chevy.BackgroundTransparency = 0
        chevy.ImageTransparency = 0
        chevy.Purchase.BackgroundTransparency = 0
        chevy.Purchase.TextStrokeTransparency = 0
        chevy.Purchase.TextTransparency = 0
print("under")
    elseif gui.Value == false then
        print("hello")


    end
    end)

It always seems to print 'under' in the output, whether the purchase is true or 'false'. The BoolValue is controlled through the Car purchase Gui.

	script.Parent.MouseButton1Click:connect(function()
		
		local PriceOfItem = game.ReplicatedStorage:WaitForChild("CheckPrice"):InvokeServer(script.Parent.Parent.Name)
		local purchase = script.Parent
		local playermoney = game.Players.LocalPlayer.leaderstats.Dollars.Value
		local purchasedvalue = game.Players.LocalPlayer.PlayerGui:WaitForChild("Camaro", 10).Camaro.Purchased
		purchasedvalue.Value = false
		
		if playermoney >= PriceOfItem then
		  playermoney = playermoney - PriceOfItem
		purchase.BackgroundColor3 = Color3.new(255,23,23)
		purchase.Text = "Purchased!"
		wait(2)
		purchase.BorderColor3 = Color3.new(255,0,0)
		purchase.Text = [[Already
		Purchased]]
		purchase.TextSize = 40
		purchasedvalue.Value = true
		print("purchased")
		 elseif playermoney < PriceOfItem then
			purchase.BorderColor3 = Color3.new(255,0,0)
			purchase.BackgroundColor3 = Color3.new(255,23,23)
			purchase.Text = [[Not enough
			money!]]
			purchase.TextSize = 40
			wait(3)
			purchase.BackgroundColor3 = Color3.new(23,255,23)
			purchase.BorderColor3 = Color3.new(0,255,0)
			purchase.Text = "Purchase"
			purchase.TextSize = 75
			purchasedvalue.Value = false
			print("not purchased")
		end
end)

Anyone can help?
