Player Disconnect

[iViscosity]

Code: Lua

1. function playerDisconnected( ply )
2.  
3.  
4.    for k,v in pairs( player.GetAll() ) do
5.      
6.       v:PrintMessage( HUD_PRINTTALK, ply:Nick() .. " has disconnected. Their SteamID is: " .. tostring( ply:SteamID() ) "." )
7.  
8.  
9.    end
10.        
11. end
12. hook.Add( "PlayerDisconnected", "leaveNotif", playerDisconnected )

I have a very simple code that's supposed to send a message to everyone when someone leaves, and giving their steamID. Right now, when someone leaves, I'm getting this in the server console:
 

Code: [Select]

Lua Error: [ERROR] addons/chatnotifications/lua/ulib/modules/player_disconnected.lua:5: attempt to call a string value
  1. fn - addons/chatnotifications/lua/ulib/modules/player_disconnected.lua:5
    2. unknown - addons/ulib/lua/ulib/shared/hook.lua:110
So I figured it had to do with the SteamID() part, so when I removed that it worked fine (said "name" has disconnected.) but then I put the ply:SteamID() back in and it didn't work. So I tried doing tostring( ply:SteamID() ) but that doesn't work either.. what do I do?

Make sure you're concatenating all the pieces that make up your string on line 6.
