Cant set the text on local script?

Ok so i cant change a text in the script but theres no error. Heres the script:

local BES = game.StarterGui.ShopGui.BESystem.ClickBE
local Camera = game.Workspace.CurrentCamera
local plr = game.Players.LocalPlayer

script.Parent.MouseButton1Click:Connect(function()
	game.StarterGui.ShopGui.BESystem.CostLabel.Text = "Cost:5"
	Camera.CFrame = game.Workspace.ShpCams.Cam1.CFrame
	if plr.Tier.Value >= 1 then
		BES.Buy1.Disabled = true
		BES.Equip1.Disabled = false
		BES.Text = "Equip"
	else
		BES.Text = "Buy"
		BES.Buy1.Disabled = false
	end
end)
