As a student researcher, I found it very much easy, simple and interesting to use it. I wanted to use for my dissertation, but the number of boxes to enter questions is limited to only five, when my survey questionnaire has more than five questions.

May I be clarified on what to enter in the responses? Say I use a 4-point Likert Scale, will I count how many responded per scale? Thank you.
