why the "ScreenGui" that i added on playergui wont showed up in the servers?

i make a portal gun that showed a "ScreenGui" when you equip it. its look fine on the studio but when you test it in the servers the ScreenGui wont showed up. here the script that i wrote.

portal = false
dimension = false
appear = false
the = script.Parent.Val.Value

function wormhole()
	local c = script.Parent.ScreenGui:Clone()
	c.Parent = game.Players.LocalPlayer.PlayerGui
	c.TextButton.MouseButton1Click:connect(function()
	script.Parent.Val.Value = c.TextBox.Text
	local wormhole = Instance.new("Part")
	wormhole.Size = Vector3.new(5,5,0.2)
	wormhole.Name = "Hole"
	wormhole.Parent = game.Workspace
	wormhole.CFrame = script.Parent.Handle.CFrame
	wormhole.Anchored = true
	local click = Instance.new("ClickDetector")
	click.Parent = game.Workspace.Hole
	click.MouseClick:connect(function(player)
		game:GetService("TeleportService"):Teleport(script.Parent.Val.Value,player)
	end)
	wait(5)
	wormhole:remove()
	end)
end
script.Parent.Equipped:connect(wormhole)
function remove()
	game.Players.LocalPlayer.PlayerGui.ScreenGui:remove()
end
script.Parent.Unequipped:connect(remove)
