(HELP NEEDED) I can't get sound.PlayURL working at all.

[SimpleGM]

I have compared this script to the wiki and another script of mine for the last hour or so and just can't understand what's going wrong. I am really new to Lua so any help is greatly appreciated.

Line 12 station:SetPos

CODE:
function playMusic()

  sound.PlayURL("https://clyp.it/r2yk0q2e","mono",function(station)

      station:SetPos(LocalPlayer():GetPos())

      station:Play()

  end)

ERROR:

[ERROR] addons/bankrobbery/lua/autorun/client/cl_init.lua:12: attempt to index local 'station' (a nil value)
