Chrome browser JS "Uncaught TypeError" error when loading a popup script on web page

Chrome browser JS "Uncaught TypeError" error when loading a popup script
on web page

Chrome browser is giving an error Uncaught TypeError: Object [object
Object] has no method 'popup' that's blocking a JS popup script on the
page http://www.t-sciences.com/product/ispatial and the other product
pages on that site, specifically on the "Schedule a Demo" button, it is
supposed to produce a form window popup.
Whenever the error is there the web page url gets appended with a # symbol
at the end of the url address, which it doesn't do in every other browser
we tested it on.
FYI here's the homepage for the "popup script" we're using. It's some
pretty basic javascript/jquery, so I'm not sure why it would get blocked
in Chrome.
