[Equest-users] User-Defined Default Expressions

OK, I am now trying to create a default expression for occupancy schedule
and I am running into more issues.
I used the same statement from my lighting schedule but here I am getting
an error "UNKNOWN KEYWORD or PREVIOUS .. MISSING"
Here is my expression I am using:
SET-DEFAULT FOR SPACE
PEOPLE-SCHEDULE = (
{switch(Local("C-ACTIVITY-DESC",0)+Local("C-ACTIVITY-DESC",1))
case "Apartmen" : #SI("ASHRAE MultiFam Occ Sched", "SPACE",
"PEOPLE-SCHEDULE")
default : no_default
endswitch
} )
I must be missing something because it seems to me like this should work
the same as it did for the lighting schedule.
Thank you,
