By 'prototype' I believe he means the record which you wish to use as a
'template'.
1. Find your 'template' record which will be used for setting the default
values of the fields in the new record.
2. Set the field.default accordingly.
3. Do not pass a record to SQLFORM. If you do, it will update that
record. It is presumed that you will wish to create a new record.
Hope that helps to clarify ValK's response.
All the best.
