HOla, i’m trying to create dyanamic function names, and I’m not sure how to do it.  
I have three buttons (“button0, button1, button2”).

var page = new Array(-470, 226, 24);  
for(var i = 0; i \< page.length ; i++)  
{  
eval(“button”+i).onRelease = function()  
{  
changePage(i);  
};  
}

this works:

[AS]  
var page = new Array(-470, 226, 24);

function changePage(\_num:Number) {  
trace(\_num)

}

for(var i = 0; i \< page.length ; i++) {  
var btn:MovieClip = eval(“button”+i);  
btn.onRelease = function() {  
// find the number of the btn via the name:  
var num:Number = Number(this.\_name.substr(6));  
changePage(num);  
}

}  
[/AS]
