If I have created empty movie clips using duplicateMovieClip(), how do I reference the movie clip instances. For instance lets say I have dupliacted 10 clips, how would I get an action to be fired when the user clicks on one of these instances? I have tried :
this[“mc”+z].onRelease = function(){},
but it does not work.

myMovieClip.duplicateMovieClip( **_newname_** , depth [,initObject])
**_newname_** is used to give a unique instance name.
for say 10 different MCs through for loop would be
for(var k = 1; k\<=10 ; k++){
\*\*\*newname \*\*\*= “MC”+k+"\_mc";
myMovieClip.duplicateMovieClip( **_newname_** , depth [,initObject])
}
In this case u will have 10 mc with instance name MC1\_mc , MC2\_mc
MC3\_mc, … so on .

[AS]\_mcButt = eval("\_mcphone"+i);
\_mcButt.onRollOver = function() {
l = this.\_name.lastIndexOf(“e”);
number = Number(this.\_name.substr(l+1, 2));
dosometing("\_mcphone"+number);
};
[/AS]
this is solution I made
problem with creating mulitple buttons that last value of variable in for loops stays so you need to retake number of your button
I am doing that with getting Number from button instance name
lastIndexOf(“e”) returns last index of letter before numbers and in case of \_mcphone that is e
if you have buttons instance names like MCxx xx is number than use lastindex of C
I sugest placing number at the end of instane names not in middle

I do it like this:
```auto
for(var k = 1; k<=10 ; k++){
var dupeclip:MovieClip = myMovieClip.duplicateMovieClip(newname, depth [,initObject])
dupeclip._x = 25
dupeclip._y = 100
dupeclip.onRelease = function(){
trace("You pressed "+this)
//etc...
}
}
```

it’s cool
in my case I must know what button number user pressed
and you can’t reference etc. like mcButton5.onRelease = function() {
showPhone(5);
}

I can respect your way of doing it, it’s actually a better way of doing it mrsteel. I just offered my way to him because it’s easier to understand when viewing it for the first time.
If i was for example to use “dupeclip” within that trace, it wouldn’t work.
```auto
for(var k = 1; k<=10 ; k++){
var dupeclip:MovieClip = myMovieClip.duplicateMovieClip(newname, depth [,initObject])
dupeclip._x = 25
dupeclip._y = 100
dupeclip.onRelease = function(){
trace("You pressed "+dupeclip)
//etc...
}
}
```
So it’s kinda stupid anyway…🙂
