The error:

[ERROR] lua/autorun/client/phtm_client.lua:32: attempt to index local 'pl' (a nil value)

Line 877 code:

	hook.Add( "PlayerBindPress", "PlayerBindPressFKeyMenus", function( _p, _bind, pressed )
		local _key = "KEY_" .. string.upper( input.LookupBinding( _bind ) );
		local _func = FKeyMenus[ _key ];
		if ( _func ) then  //Line 877
			_func( LocalPlayer() );
		end 
	end);

I can't figure out as to why I keep getting this annoying error.

Please help.

Don't just call
[lua]hook.Call("TeamCheck")[/lua]
You have to give it arguments, use hook.Run instead, it does the same but it's simpler
[lua]hook.Run( "TeamCheck", pl )[/lua]
Replace your hook.Call with that.
