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

[Ceph]

I am trying to get a menu to pull up through the F1 key, which works because it calls up my function from cl_init.lua, but I keep getting the same error every time. "attempt to index global 'vgui' (a nil value)". Even when I remove the part that is included in the error, it just shifts down to the next part of the vgui, telling me the same error. I looked it up on the wiki, and the definition is too vague for me to understand. Here is my cl_init.lua:

include( "shared.lua" )

function set_team()

You are calling it server-side. The vgui library only exists client-side.

You are including cl_init.lua serverside.
