I have created a survey with some mandatory questions.

I have got so many incompleted responses (All blank).

How can I prevent those incompleted responses?

I am wonder if someone not fill those mandatory questions and then click "Submit" button but can save into the incompleted responses.

Please HELP!!!

All blank : user start the survey but don't go at end of the survey.

If you select only 'complete' response : did you have this blank answer .

I know that it will save as an incompleted response when I click "next" in the welcome message. What should I do to prevent so many incompleted response? Thanks.

I really don't see how you can prevent this .
You can not disallow your user to close browser when they want (you don't have even if you can ... only 'spam' webserver use this).
