Attempted to call method 'Nick' (a nil value)?!

[sackcreator54]

I am trying to display a user's username in a panel. I'm using

function playerstats(ply)
local playername = ply:Nick()
draw.DrawText(playername, "DermaLarge", ScrW()/12, ScrH()/10, Color(255, 255, 255), TEXT_ALIGN_LEFT)
end

When I open the panel In game, my console is spammed with

[ERROR] gamemodes/squadrush/gamemode/menus/cl_f2.lua:15: attempt to call method 'Nick' (a nil value)
  1. unknown - gamemodes/squadrush/gamemode/menus/cl_f2.lua:15

I don't know why this is not working.

The player passed to playerstats is nil

Nevermind, I just used for k,v in pairs (player.GetAll()) do.
