Ajax Reload for the Calander Availablity

Hi, Im using The Appointment + and MarketPress.

Currently we have the following shortcodes on the page

I want to integrate Ajax so when user selects drop down the page info will automatically update. Currently im not sure why when clicking the button nothing happens? - is this a bug?

Is this the shortcode that enables ajax? [app_service_providers autorefresh="1"]
tried using this one but cant get it to work ?

ajax
If set as 1, Services thumbnails and descriptions will be loaded by AJAX. Recommended for sites with many services
Example: [app_services ... ajax="1"]

Support Access is open for the next 5 days.

Please dont post any brand related information/ screenshots or domain links as i have had issues with google caching this information and linking it to their google searches of my site ... very bad for brand... please use temporary image upload / tiny url / pastebin etc to mask this information.

Thanks

Tom
