I am having extreme difficulty accomplishing item #3 listed below.
Once I get the system to select location and service provider, I can't figure out how to select only the services offered by selected service provider.
What sequence of Shortcodes should I use to:
1. Select location first.
2. Then select a list of service providers, but only those ones that service the above selected location.
3. Then select services, but only those services that the above selected service provider offers.
