Disappointed

After loading and activating the charboot-for-wordpress-gs plugin into WordPress version 3.9.2 on my web-site, the new Media icon is present during a page edit, but ‘clicking’ the icon (left mouse button) is without effect!
FireFox Console shows a js error in:
/wp-content/plugins/charboot-for-wordpress-gs /js/customgs.js
reported as:-
“TypeError: jQuery(…).dialog is not a function [customgs.js:14]”
When ‘clicking’ the icon with the middle mouse button, the Google Charts Editor is displayed in a new browser tab, and works perfectly except it is unable to send the shortcode to WP.
This is a shame as the plugin is just what’s needed.
Any assistance with this would be very much appreciated.
