The Code Line
local job = GAMEMODE.Jobs:GetPlayerJob( pl )

local license_id = GAMEMODE.Player:GetSharedGameVar( pl, "driver_license", "None" )
local nameFirst = GAMEMODE.Player:GetSharedGameVar( pl, "name_first", pl:RealNick() )
local nameLast = GAMEMODE.Player:GetSharedGameVar( pl, "name_last", "" )
local gender = GAMEMODE.Player:GetSharedGameVar( pl, "char_sex", 0 )
-- gender = gender == 0 and "Male" or "Female"
-- job = job and job.Name or "Unknown"
license_id = license_id ~= "" and license_id or "None"
