birthday arrays and pulldowns with error handling

/ Published in: Smarty

it's an excerpt of a registration form with 3 pulldowns for birthday ( day, month, year )
check for empty vars and applying CSS classes to show error on "empty" fields.
there are probably better ways, but this works for me. any suggestions welcome.
