First of all, you're trying to use the STRING 'NOW()' as a
default value in a DATE field. MySQL will try to convert this
string to a date on every insert, fail, and use the zeroed date
instead.
Secondly, MySQL does not accept functions as default values.
You should use the function only on INSERT.

ERROR cannot be a default value, unless you specify it as part of
the enumeration. If you need TRUE/ERROR, define ERROR instead of
FALSE. If you need a tri-state value, use 'TRUE', 'FALSE', 'ERROR'
as the enumneration values.
... or I don't get what you're trying to do...
