[Freeswitch-users] Wrapping $1,$2,etc.

[Mimiko]

Hello.

I've searched the wiki for some mention, but to nothing.

I have a phrase to say. For this I capture digits with condition: <input 
pattern="^([2-9])([1-9])$"> . So $1 is for first part to say and $2 is 
second. I have files for first part named like 10.wav, 20.wav, 30.wav 
and so on. For second part I have files named like: 1-2.wav, 2-2.wav, 
3-3.wav...

I can use for second part:
  <action function="play-file" data="digits/$2-2.wav"/>

But I have problem for first part:
  <action function="play-file" data="digits/$10.wav"/>

This plays nothing. How to delimit that the variable is $1 and not $10 ?
