Using javascript in Wordpress Chronoforms5

I've moved a form from Joomla to Wordpress but I get the following Fatal Error:
Uncaught Error: Class 'JHtml' not found in /home/anglicanfuture/anglicanfuture.org.au/wp-content/plugins/chronoforms/admin/chronoforms/actions/js/js.php(33) : eval()'d code:2 Stack trace: #0
The form is at anglicanfuture.org.au/register
Is there something I can add to Chronoforms5 or the Wordpress site to allow javascript to work in Wordpress?

Hi cappleby,

The problem is in Line 2 of some Custom Code you have in the form. You'll need to check that and make sure that is WordPress compatible.

Thanks. In case others are trying to do the same thing, the Joomla version of the form has a java script element that uses a call to the Joomla library:
<?php
JHtml::_('jquery.framework');
?>
But that doesn't work in Wordpress.
Instead I needed to de-register the WP version of jquery then enqueue a new version of jQuery:
<?php
// include custom jQuery
function shapeSpace_include_custom_jquery() {
wp_deregister_script('jquery');
wp_enqueue_script('jquery', 'https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js', array(), null, true);
}
add_action('wp_enqueue_scripts', 'shapeSpace_include_custom_jquery');
?>

jQuery(document).ready(function(jQ) {
jQ('#Fees').click(calc); ... etc.
