[Freeswitch-users] how to use session:playAndGetDigits with the "say" command in lua script?

I'm trying to convert an example from a dialplan: http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_play_and_get_digits#Exa... <extension name="play_and_get_digits with say"> <condition field="destination_number" expression="^(6500)$"> <action application="play_and_get_digits" data="1 1 1 3000 # say:'press one for technical support' silence_stream://250 res \d+" /> </condition> </extension> into a lua statement like this: digits = session:playAndGetDigits(1, 1, 1, 3000, "#", "say:'press one for technicial support' ", "say:'invalid entry'", "\\d+") but I'm having trouble with the quoting. The log says: 2011-06-22 14:40:52.614654 [ERR] switch_ivr_play_say.c:1144 Invalid Args I can't find any lua examples that use both playAndGetDigits and "say" any suggestions?
