This is an interesting one and not specific to the quiz. One gets this problem whenever one tries to use insert_record to insert a record into the database that contains a field which has the string value 'null'. This is a fault in the adodb database abstraction layer that does not distinguish between the string null and null.

I am assigning this bug to Martin.
