Bob,

You also need to define the conditional booking profile as the default for the domain. This was the response I got when I asked the same question of support two months ago. These were with 5.5.

There are 4 things needed to setup conditional booking.

1. Set the Service Provider as "Do Conditional Accepts"
2. Create a Conditional Booking Profile
3. Via Domain Settings set the Domain's Conditional Booking Profile
4. Update Workflow Parameters to include the mode.
"BOOKING_MODES" and "CONDITIONAL_BOOKING_MODES"

If needed to accept Null Service Provider values automatically change this parameter to True "COND_BOOK_ACCEPT_SPV_WHEN_PV_IS_NULL"
