about my appointment

category B2 VISA inquiry.

i filled my DS 160 form and got the confirmation page. i then proceeded to schedule an appointment. the date i chose was not the same date i saw on the instructions page. i thought i could fix it by correcting an error in my DS 160 form. i retrieved my form, and corrected a few things then got another confirmation page. my worry now was how to reschedule the appointment coz the date they gave me was in the same month i intended to travel. so i went ahead and rescheduled my appointment for a closer date. i finally succeeded but now my question is, the rescheduled appointment instructions page still carries the old 10 digit alphanumeric code for the old DS 160 confirmage page and not the corrected one. please what can i do now?
