TTT Specialrounds errors!

[KingCentKing]

Hi guys
I tried to install the ttt specialrounds plugin for ttt from coderhire (free addon) but
i got this error:

[ERROR] lua/hud.lua:10: attempt to index global 'surface' (a nil value)

Here is the code of the hud.lua

Where did you put the file? This error usually happens when you try to include a clientside file on the server, since the surface library is only available to the client.
