I would use a text entry question type, but I need to have two other options available (refused, don't know).
I couldn't use custom validation (regex 0-30) because that required something be entered, when the respondent could select one of the other two options.
I guess more generally, how can I add radio choices (refused, don't know) to questions of other types (e.g. text entry, matrix, ect.)
