[ERROR] addons/centre-help/lua/autorun/cl_frame.lua:2: attempt to index global ‘input’ (a nil value)

  1. fn - addons/centre-help/lua/autorun/cl_frame.lua:2
  2. unknown - addons/ulib-master/lua/ulib/shared/hook.lua:109

It’s erroring because you’re running this hook Serverside, when you should only run clientside, as the functions you’re trying to use and else are only clientside.

Drop cl_frame.lua into autorun/client/
