Regarding GIVEN NAME in DS160 form

my given name in passport is ‘A’ ‘B’(A- my name,B-My fathers name).but while filling DS 160 form i have filled only “A” in GIVEN NAME column. i have already paid the fees and scheduled the appointment. will my visa form be rejected ? how to correct it in case needed?

fill another DS-160 and get in touch with stanley (ustraveldocs) team to link the latest DS-160 number to your appointment
