I think the title is self-explanatory.

I've been wondering how to combine the desiderative (たい) and the conditional
(えば/たら). For example, if I want to say "Excuse me, what should I do if I want
to smoke here", it thought it would translate to
"失礼{しつれい}ですがここでたばこを吸{す}いたければどうしたらいいですか", however I'm not sure whether that's
correct or not. Also, if possible, could someone also provide a few examples
of how to use both たい+えば and たい+たら so I could grasp the difference and meaning
properly? Thank you in advance.
