Hi Denis... I'm still working on this
Downloaded po/mo files, I've done everything with the instructions by the LS website.
I've edited the *.po file and I've added the translations substituting all occurences of 'comment' and 'Comment' with my string which is 'Suggestions'.
Saved and putted the .mo file in the right directory.
I activate my survey and I can see all my updates of the translation
in the admin interface, but when I click 'Print your answers' function,
the text 'Comment' is still there in every questions having type (Multiple choice with Suggestions)...
Any ideas??? Thx!
