I have solved the problem.
For those who might be interested, I changed
$('#pack-method').on('change', function() {
if (this.value === 'Pallet') {
$('#hidden2-1').show();
$('#hidden2-2').hide();
}
...
}
to
$('select').on('change', function() {
var a = $(this).val();
if (a === 'Pallet') {
$('#hidden2-1').show();
$('#hidden2-2').hide();
}
...
}
