Appointment + Help

I installed Appointments + and added in the short code to display the calendar. However, that's all its doing. Click on the day, another table opens up, but click on the time and nothing happens. Nobody can make an appointment. Do I need to add another shortcode to do that?

Site in question is http://www.galtmilemedia.com/contact-us/

Need to figure out how it works here before I apply it to my client sites.

Thanks
