Question on DS160

[ravi.mahadasa]

I booked my H1b visa stamping appointment and paid the fee. While booking the appointment I gave a DS-160 form number without completely filling or submitting the form. I am able to book the stamping appointment but later when I try to retrieve the DS160 form, it's saying data invalid(First 5 characters of surname or year of birth). Maybe something went wrong. Can I fill a new DS160 form and submit and go to stamping with the already booked appointment?
Please clarify as this is urgent.. Thanks!!
