Error: attempt to index global 'vgui' (a nil value)

I keep running into this error when I am working with derma. I'm trying to open a derma panel when a player presses f1.
Error in the console: [ERROR] gamemodes/benstdm/gamemode/teamselect.lua:2: attempt to index global 'vgui' (a nil value)

Vgui is clientside.

Include teamselect.lua on client, not server

Include teamselect from cl_init instead. Keep it AddCSLuaFile'd tho
