How do you check the leaderstats to see if the player is a certain "Tier" (or level)?

I'm trying to make a game with an equipment GUI, and I encountered an error.

My script is below.

script.Parent.MouseButton1Click:Connect(function()
	if game.Players.LocalPlayer.leaderstats.Tier.Value >= 5 then
	game.Players.LocalPlayer.EquippedTool.Value = tostring(script.Parent.Name)
	script.Parent.BorderSizePixel = 5
	script.Parent.ZIndex = 2
	for i, image in pairs(script.Parent.Parent:GetChildren()) do
		if image.Name ~= script.Parent.Name then
		image.ZIndex = 1
		image.BorderColor3 = Color3.new(0,0,0)
		image.BorderSizePixel = 1
		end
	end
	script.Parent.BorderColor3 = Color3.new(255,0,0)
	script.Parent.Parent.Parent.TextButton.Text = "Currently Equipped: "..script.Parent.Name
		else
		script.Parent.Parent.Parent.TextButton.Text = "You need to be at least Tier 5 for this!"
	end
end)

It comes out with an error that says "Tier is not a valid member of IntValue"

I have no idea how to fix this.

Thank you!
