If you want the datamanager to update a field, you need to first make sure it is in the datamanager array - in this case the one for the User datamanager (in class_dm_user.php). You'll have to add it to that array $validfields there. You'll want to read the code for the fields that go into the usertextfield table since they go into a separate table and are treated specially and you will have to do the same with your field5 (it goes into the userfield table).
