We're using the modified version of this plugin so that we may employ drop-down lists (DDL). I have a Country DDL which is required, however it is possible for a user to submit the form without selecting a country. Sometimes the user is then directed to where he should, sometimes a 404 pops up.
I'm wondering if this is because the first option in my DDL is null, formatted as such: " : | " using spaces.
Is this it or is there something trickier involved?
