The problem is with your selector. You are giving a partial name, but with the syntax you are using it expects the complete name.

So try something like:

var birthdate = $contactForm.getElement('select[name^="birthdate"]').getProperty('value');

However this is only going to get you the first element that matches.

So with MooTools, you could do something like:

$$('select[name^=birthdate]')

Or in JS:

document.querySelectorAll('select[name^=birthdate]')

Hope that helps
