I have build a online questionnaire with 20 question. Each question is on it's own page with a "next" button – which saves the answer along with the user id.
There are separate tables for every question.
At the end there are one page that shows a summarize of questions and answers.
Now, the client is asking if it possible to let the user leave off in the middle and continue at a later time. Can this be done? How to do it?
Any other way to manage this?
