This is a sample script that I use to save preferences. The key to making this work is to declare all your UI variables with a name. Then you have to give the UI control a name that is the same as the variable. What's nice about this, is that you can add control items and it will automatically update.
///////////Preference and XML vars
var presetList = new Array( );//Blank array to be populated with the users preferences stored in an XML file

if(xmlFile.exists){
prefXML = new XML(readXMLFile(xmlFile))
};// see if a preference file exists and load it.

alert('There is no preset file')}
