Hi,
Thanks for your reply. I've tried to do it as you said but it does not seem to work.
I've attached some screen shots of 1) Check box field value/label settings, 2) Language override settings, 3) Registration page.
As I said before, these language overrides work well with check box field titles but not in the labels within check boxes.
Note that I'm also using CB Profile Pro plugin. Not sure if that could effect this.
