JavaScript error

Hello, I just purchased and installed WP Easy Gallery Pro and am having trouble with the plugin. This is the gallery in question: http://www.kimmacquarrie.com/photos/peru/machu-picchu

I created a new page and added the shortcode that was provided. Only one thumbnail is coming through (how do I get them all to show up?) and when I click on the photo, I get a JavaScript error in Chrome:

Uncaught TypeError: Cannot call method ‘open’ of undefined machu-picchu:79
onclick

I am running version WordPress 3.8 and WP Easy Gallery Pro 3.5.

[EDIT] I already tried deactivating all other plugins and then testing, but the issue is still happening.
