Additional context

The solution is quite easy: make the field mandatory and show in the 'help-text' what options are avialable (by example '0' for a working brievenbuspakje).

Beside that, it looks to me that the test for null-value should/could be improved, because an optional field can have a NULL-value and the extension isn't handling them correctly right now.
