2 confirmation pages for DS-160 form

[rmukt]

I made a mistake while submitting DS-160 form, now re submited the document, but got a new barcode .. Will that be a problem?

In the section where you schedule your visa interview appointment, there is a section called "Profile". In that, next to your name, there will be a small "Edit" button. Click on it, and enter the new barcode number in the appropriate text box where it says "Confirmation Number" or something like that.

Take both. You would need to update the correct DS-160 confirmation barcode on your appointment.
