MeetMeCount on Asterisk 1.6

Warning - Asterisk newbie

I am trying to setup up MeetMe with a max user count of 10. In addition, I would like Asterisk to play how many parties are on the bridge. I have been trying to get this example to work in Asterisk 1.6 without any success:

CONFMAX => 10 ; max persons in conference

exten => 8081,1,Macro(stdmeetme,8081))

; with limit to max number of persons in conference

exten => s,1,MeetMeCount(${MACRO_EXTEN}|count)
exten => s,2,Gotoif,$[${count} >= ${CONFMAX}]?103
exten => s,3,MeetMe(${MACRO_EXTEN})
exten => s,4,Goto(s|1)

exten => s,103,Background(conf-full)
exten => s,104,Hangup 

Any help would be appreciated.


syntax :

exten => s,2,Gotoif,$[${count} >= ${CONFMAX}]?103

should be:

exten => s,2,Gotoif($[${count} >= ${CONFMAX}]?103)
