Schedule the survey by choosing for how long to set it live, when to be triggered to your audience and whether or not you want to receive an email when it has expired:

Last, but not least, Rename the survey, preview it before setting it live and then PUBLISH it.
That’s it! You’re ready to go!

 

DON’T FORGET : After each modification you have to wait 3-4 minutes until it will be visible in the front end.
