Appintments+ buttons don't work

Hi Rupok,

Thanks for your reply,

Here are the links:

http://www.phoros.eu/fr/consultations/
http://www.phoros.eu/make-an-appointment-3/

In the make an appointment page here's how the shorcodes look like

[app_all_appointments]
[app_confirmation]
[app_monthly_schedule]
[app_confirmation]
[app_login]
[app_service_providers]
[app_confirmation]

I can select the dropdown but there's not interaction whatsoever.
Thanks for your help.

Regards

Alaric
