other_option survey

Hello,
You need to click on Other option to display the comment field.
Please add the following Keyword in vQuiz language file ( components/com_vquiz/language/en-GB/en-GB.com_vquiz.ini ) OTHER_OPTION="Other"

I want to make a survey and I can't find the "Ability to set either a comment box or “Other” option to take user comment or review to the question."

I choose "other option", so that the user has the ability to write a comment in the comment box, if no proposal applies. But there ist no comment box.

1. In the frontend I just can see "other_option" and no comment field
2. Where can I translate other_option into german? I can not find it in the english language file?

Thanks

Regine
