I have the following lines of code that i want to optimize:

[AS]furniture1.onRollOver = function() {  
duplicate(furniture1);  
};  
furniture2.onRollOver = function() {  
duplicate(furniture2);  
};  
furniture3.onRollOver = function() {  
duplicate(furniture3);  
};  
furniture4.onRollOver = function() {  
duplicate(furniture4);  
};[/AS]

I tried the following but it wasnt working for me:

[AS]var numOfFurniture = 4;  
for (var i = 1; i \<= numOfFurniture; i++) {  
var furn = this[“furniture” + i];  
furn.onRollOver = duplicate(furn);  
}[/AS]

how can i optimize this so i dont have to write an onRollOver statement for every piece of furniture i add?

thanks in advance.
