need to reload page for form to work

Hi,

I have added some script to the top.php in order to run a form. The form does work but only after the page has been refreshed. I have deactivated all the plugins and the problem is still there - in IE10,Firefox, Chrome & Opera. Your help would be greatly appreciated.

The page in question is http://www.pro-holistic.co.uk/on-line-stress-level-evaluation/

The added script is: -

<script type='text/javascript'>
// updatepage();

$(document).ready(function() {

$('#btnStressTestSubmit').click(function() {

var totalChecked=$('[name="chkChoice"]:checked').length;

if(totalChecked<=7){
ShowResults(1);
}
if(totalChecked>=8 && totalChecked<=14){
ShowResults(2);
}
if(totalChecked>=15 && totalChecked<=21){
ShowResults(3);
}
if(totalChecked>=22){
ShowResults(4);
}
});

function ShowResults(resultPanelNumber){
$('#questionPanel').hide();
$(document).scrollTop(220);
$('#result_'+resultPanelNumber).show();
}
});

</script>

I have found how to stop this from happening but it is really not a proper fix. I have disabled "Load Content Dynamically" and the form works first time, every time.

Is there a proper fix for this where I can still have content loading dynamically and have the form work properly?
