[Freeswitch-users] lua script

[Muhammad Shahzad]

classical variable scope problem. :-)

http://lua-users.org/wiki/ScopeTutorial

Basically, you should declare variable above and outside IF condition and
initialize it say 'nil', then change its value in IF per logic, finally
outside below IF block check if variable value is other then 'nil', if so
then do your operation. This is very basic programming man!

Thank you.
