You could do it like this:

- name the imageMC’s: imageMC1, imageMC2, imageMC3 etc.
- on the button place something like this:

```auto

on(release){
  // if there are 3 imageMC's
  myTarget = Math.round(Math.random(2)+1);
  _root["imageMC"+myTarget].play(); 	
}

```

_Math.random(2)_ gives you a random value between 0 and 2  
_+1_ makes this a number between 1 and 3.  
_Math.round()_ rounds this value to the nearest integer, e.g. 2.132 will become 2

Note that in this case if _myTarget_ would equal 2, then _\_root[“imageMC”+myTarget].play()_ would tell _imageMC2_ to start playing.

Hope I’ve explained everything correctly =)
