Mistakenly Selected B1 instead of B2 in DS - 160 form

[Paka]

My Parents are attending B2 VISA on May'3rd-2011. Unfortunately my Father DS 160 form was mis-spelled as he is appearing for the B1 VISA. My Mother Application form is fine, it clearly stated as B2.
Is there an way that I could modify the DS Forms now? Will that be any Problem? Please, need suggestions on this...Thanks in Advance.

I have the same problem but I become aware of this 2 days before my flight (02.08.2011) I was looking through my documents and come into the visa-application and there was by mistake written that my purpose is business (B2) instead of tourist (B2). Nevertheless at the meeting with consul I stressed that i am visiting USA for tourist purposes. I have found out that I have the visa B1/B2. SHould I worry about the speech with the officer at the airport in the USA???

Your father can point out this mistake at the time of interview to VFS personnel and also to VO. They will make necessary correction. Nothing to worry now.
