[jQuery] submit() not submitting

[l3kris]

I have this function that validates and is supposed to submit a simple
form:

$(function() {
$('#godkend').click(function() {
  if($('#Select1').val() == "") {
    alert('Du har ikke valgt første');
  } else if($('#Select2').val() == "" && $('#Select2').is(':visible'))
{
    alert('Du har ikke valgt anden');
  } else if($('#Select3').val() == "" && $('#Select3').is(':visible'))
{
    alert('Du har ikke valgt tredje');
  } else {
    alert('fint');
    $("form:first").submit();
  }
});
});

The validation works fine, but the submitting doesn't. The test (alert
('fint')) pops up allright, so what should I change?
