--Right:
function idChatPlayernames:updateParty()
    local Unit, Name, Class
    for i = 1, GetNumPartyMembers() do
        Unit = 'party' .. i
        name = UnitName(Unit)
        _, Class = UnitClass(Unit)
        self:addName(Name, Class)
    end
end

-- wrong part:          _, Class = UnitClass(unit)
-- wrong variable: unit
-- right variable: Unit
