I declared the folowing fuction for the onRollOver -and onRollOut state of three buttons:

[AS]this.onEnterFrame=function(){  
for (var i in this){   
if (this\*._name.substr(0, 6) == "sound_")  
{   
this\*.onRollOver = function() {   
new Color(this).setRGB(0xCCCCCC);   
}   
this\*.onRollOut = function()  
{   
new Color(this).setRGB(0xA4Ae8B);   
}   
}  
}  
}  
[/AS]

I also want to add an onRelease state wich overwrite the onRollOver -and onRollOut part of the function and set the new Color to (0XFFFFFF) and start a new song. The first part of the function should work again when one of the other two buttons is pressed.

I tried it by adding the following code, but it isn’t working:

[AS]this\*.onRelease = function() {  
delete this\*.onRollOver;  
delete this\*.onRollOut;   
new Color(this).setRGB(0xFFFFFF);   
}[/AS]

What am I doing wrong?
