Validity of DS-160

[shiv22sri]

I have question regarding validity of DS-160 form.
I have read that DS-160 will be valid for 1 month only. What if I fill DS-160 for my parents on 5th January 2016 and pay the fee, and schedule their interview after 10th February 2016. In this case already filled and paid DS-160 will get deleted and I will need to fill another one? Or is there something like, validity of DS-160 is for 1 month only if you do not pay fee?

You can fill the DS-160 form and schedule their interview whenever the interview date is available. You may get interview date after a month or 2 does not matter.
