Shortcode within a form isn't working properly

Okay, so here is the issue I am having. I'm using Gravity forms on a site here...

http://www.lowercolumbiacap.org/energy-assistance-appointment/

I've set the form up with some HTML blocks and within those HTML blocks I've included some shortcodes for a plugin called Appointments+.

Now the short codes are working because the calendars are showing up just fine. However, when you click one of the available dates on the calendar (they are green in color) it should populate the white space to the right of the calendar with the available time slots.

When I move the Appointments+ shortcodes outside of the Gravity Form (and just place them in the page itself) this function works just fine. So, somehow the shortcode being within Gravity Forms is causing that function not to work.

Any ideas on what the issue might be? I really want to get this working because it's going to really simplify the signup process for an upcoming event.

I did contact them and they said to contact you guys, haha. I'll assume that I probably won't get anywhere on this.

What I think I'll do is iFrame those appointment calendars and that should work since it will be on an entirely different page all together (hence the iFrame).

I wish Gravity Forms would build some sort of 'add-on' for appointment scheduling like this. You'd be surprised, theres tons of them out there but this Appointments+ plugin is the only decent one I could find, and even then it's seriously lacking.

I'll bet Gravity Forms could build a really nice one =]
