Old Passport lost and DS 160

[akshaymittal]

Hi,
My last visit to US was in 2001 when I was 11 years old. I am not able to find my old passport which contains the US visa.
Can anyone please tell me what should I fill up in the previous visa details section in DS 160 form.
Thanks.

Any updates on this?

I'm in a similar situation.. How did you manage in the end? Some details would be useful, and deeply appreciated. Thanks!
