Booking Timeslots - Bookings not blocking out on calendar

Hi,

I love this module (the demo is great) but can't seem to get the last bit working. I am looking for some Drupal'ers out there with some more PHP experience to give me a nudge in the right direction.

I have installed the module, this works correctly:

1. 'book now' is on the calendar OK
2. click 'book now' takes you to the content type to book the time OK
3. submit content type works OK, node is created and exists in Content

my only issue is the time does not get visually 'booked out' in the Calendar. So I am thinking of a few possibilities?

1. Is my view set up incorrectly?
2. Should I be checking anything else (common issues with this module)

any direction / advice would be appreciated, thanks.

s.
