Networking Help

[Velocity]

So I've been trying to make an addon for muting an individual player in-game with a menu.

But I am having trouble with networking the menu to make it so that on a command said in chat it opens a menu.

cl_init

net.Receive("menu", function(len)
	local base = vgui.Create("DFrame")
	base:SetPos(ScrH()/2, ScrW()/2)
	base:SetSize(200,300)
	base:SetTitle("Players")
	base:SetDraggable(true)
	base:ShowCloseButton(true)
	base:MakePopup()
	local p = vgui.Create("DListView")
	p:SetMultiSelect( false)
	p:AddColumn( "Players" )
	p:AddColumn( "SteamID" )
	
	for k,v in pairs(player.GetAll()) do
    p:AddLine(v:Nick(),v:SteamID())
	end
end)

init.lua

util.AddNetworkString("menu")

function chatCommand(ply, text, public)
	if string.sub(text, 1,4) == "/mute" then
		net.Start("menu")
		net.Send(ply)	
	end
end
hook.Add( "PlayerSay", "chatCommand", chatCommand );
