Scheduler not working

Hello,
I activated the plugin with wordpress and I place the short code [[scheduler_plugin]] on the page I would like it to be viewed on www.bluehillsroom.com/cal but all i’m getting is an empty box. How do I get the calendar to show?

And once I do. Is there a way I can edit the calendar on that webpage and not in the wordpress dashboard? Like the demo at

Thanks for your help
