Ho questo codice:

codice:
	import flash.events.EventDispatcher;
	
	public class ConfigManager extends EventDispatcher {
		
		// The name of the event to be fired when configuration is read
		public static const CONFIG_LOADED:String = "configLoaded";
		
		// Location of the config xml file
		public static const CONFIG_XML_URL:String = "config/config_carousel.xml";
		
		// URL of the data xml file
		// var external_text = this.loaderInfo.parameters.sdata_carousel;
		public static const DATA_XML_URL:String = "carousel.asp";

...
se volessi sostituire carousel.asp con una viariabile sdata che prelevo dalla pagina stessa con

so.addVariable ("sdata","carousel.asp")

come posso fare ?
