Random voices

I want to play a random mp3 file 1 of 10 with a VM2.  I now know how to make the VM2 work.  What I need to learn is how to generate a random number from 1-10 after a trigger is triggered and play voice(x).mp3 were x is the random number.

This is what I have so far.....

This will do what you want: it will play voice01.mp3, voice02.mp3, voice03.mp3 ... voice10.mp3; note that the files less than 10 have a leading zero in the name. 

Also note that I'm using the RX input to detect the presence of the VM2 and the start and end of the audio; this is the only reliable way to do what you want.  Please trust me on this; the VM2 is junk (my opinion) and you cannot count on it unless you're getting feedback from it.
