Problem with default values in required fields

We've got a form, and there are a couple of fields that are required that we have defaulted the most "common" responses. When we do this, the form errors with please chose a value. We did.. we took the default!

Here's a link to the form, feel free to play with it.

Never mind... Just figured it out... Since there is a default value, it doesn't need to be required. Removed the required checkbox, and works fine.
