Plugin throws an error when in debug mode

I’ve installed this plugin on a site that is in development mode and this plugin throws out a chain of notices on the front end of the site, such as the following:

Notice: wp_enqueue_script was called incorrectly. Scripts and styles should not be registered or enqueued until the wp_enqueue_scripts, admin_enqueue_scripts, or login_enqueue_scripts hooks. Please see Debugging in WordPress for more information. (This message was added in version 3.3.0.) in /home/user/site-xyz/wp-includes/functions.php on line 4231

The plugin still works as expected, and the notices go away when the debugging mode is turned off, but this error should be corrected with the scripts.js file enqueued properly.

thanks!
