Hi

If I have the name of the function I want to run in a string called function\_name and the params I want to pass to the function in another string called function\_params, how would I could this to go in a button with the following code:

mc.button1.addEventListener(MouseEvent.MOUSE\_DOWN, button1\_handler);  
function button1\_handler(Event:MouseEvent):void {  
// Dont know what to put here  
}
