In DS-160 Missed to Add eductional detail. What to do?

Am applied for H1-B Visa and I have missed to add eductional information in DS-160, I have marked that option as NO. Will it effect my visa interview. What to do now. I have already done my OFC today.

Is that create problem in visa approval.

You can complete another DS-160 form, and carry both for interview. You can let the interviewer know about the error and see if it can be fixed there. You should check w/ others as well who have undergone this.
