can i resubmit the ds-160 form for the third time after i have booked my visa appointment slot?

i have submitted the ds160 form and booked the visa appointment using the first ds-160 form. Later, there were some corrections. Hence i resubmittted it and now i got documents from my employer specifying a little change in my salary. Can i resubmit the ds160 form for the third time? If Yes, do i need to carry all the three ds-160 confirmation pages or the last one which is the correct one. Please help. Its urgent. i have my interview scheduled the next week.

You can create or submit multiple DS-160. but your appointment is only linked with one.
so you need to carry only the last one, the one used for booking appointment.
