Getting HAT Find Message to work

I'm trying to figure out what I have to set where to get the HAT Find 
Message feature to work. On my orchestration I enabled tracking for
message 
properties. But when I go to HAT Find Message and choose a schema for a 
message sent to my orchestration with a promoted property, the Property
drop 
down list in the Message properties filter section of the window has no 
properties in it. What do I have to enable where to get my promoted 
properties to show up in that list? Should I be enabling tracking of
message 
properties in the appropriate send or receive ****t in addition to or
instead 
of in the orchestration? Is there something other than enabling tracking
of 
message properties that I need to do? Are the promoted properties supposed

to show up in this list? For me the list of properties is always empty. I 
want to be able to find messages for a specific order number and most of
my 
messages have order number as a promoted property.

Thanks,
Zoe
