Thank you! Or should I say, without typos this time, どうもありがとうございます!
Your good translation made me examine my own not so good translation again, and I think I now understand the second line:
でも、一つだけありません。 Which, if I break it down, says roughly, "But, one thing only there is not." Which makes more sense in English as "There is only one thing missing." That makes sense. I appreciate your help!
どうもありがとうございます!(I'd better practice that one some more!)
