I've created an approval process exactly as described between pages 26 and 27.

I've activated this process.

I've created "Mileage" objects for well over 200 miles.

However, these new records are not locking, their approval status is not being set, no e-mails for the approval process are being sent (those for the large mileage, are however).

Any idea what else -- other than activation -- might prevent this process from kicking in?
