Survey pages can be more informative and visually appealing if they display the total amount of questions and the number of question that the user is currently viewing, like "Question 2 of 5". When you have only a few questions, this progress report often increases the user's likelihood to complete the whole survey instead of abandoning it part of the way through. This is not included in NationBuilder survey pages by default, but you can display this by adding the following code to the template of your survey page:

{% for question in page.survey.survey_questions %}
{% if question.id == page.survey.next_question.id %}Question {{ forloop.index }} of {{ page.survey.survey_question_count }}{% endif %}
{% endfor %}

Pro-Tip: Studies have shown that it is best to display this below the survey question rather than above it.
