Please try adding this script to your BYO:
<script>
$(document).on('ssi_ready', function(){
// Parameters
var attributeToShow = 3;
// Run
var answered;
$('input[name="hid_list_[% QuestionName() %]"]').val().split(',').forEach(function(attribute){
if (SSI_GetValue('[% QuestionName() %]_' + attribute)) {
answered = true;
}
});
if (!answered) {
$('#[% QuestionName() %]_row_' + attributeToShow).show();
}
})
</script>
Line 4 should be updated with the attribute number to be shown on page load.
