I did explain it above but will again here.
The above ones work, the ones you provided.
<script type='text/javascript'>
$(function() {
$('#bandName').change(function() {
var x = $(this).find('option:selected').text() +" "+ $("#vID").find('option:selected').text();
$('#keywords').val(x);
});
});
$(function() {
$('#vID').change(function() {
var x = $("#bandName").find('option:selected').text() + " " + $(this).find('option:selected').text();
$('#keywords').val(x);
});
});
</script>
But now I have a field called specialGuest, it's just a text field and I want the value of that field to also populate into the keywords field after it's typed in.
