[asterisk-users] syntax error from digium fax manual ??

[sean darcy]

I've cut and pasted from the digium fax admin manual:

exten => send,1,NoOp(**** SENDING FAX ****)
exten => send,n,Wait(6)
exten => send,n,Set(GLOBAL(FAXCOUNT)=$[ ${GLOBAL(FAXCOUNT)} + 1 ])
exten => send,n,Set(FAXCOUNT=${GLOBAL(FAXCOUNT)})

     -- Executing [send at sendPDFasFax:1] NoOp("DAHDI/4-1", "**** SENDING 
FAX ****") in new stack
     -- Executing [send at sendPDFasFax:2] Wait("DAHDI/4-1", "6") in new stack
     -- Channel 4 detected a CED tone from the network.

     -- Executing [send at sendPDFasFax:3] Set("DAHDI/4-1",

   == Setting global variable 'FAXCOUNT' to ''

The error seems to be saying that I need a closing "}" or "]", but it 
looks like it has closing brackets.

Any suggestions?
