Help Adding Menu Items to Bridge

Question

I've created (modified) a couple of Bridge Scripts and finally have them working nicely. Now, I want to add a couple of Menu Commands to execute them. I tried modifying a script in the SDK, SnpAddMenuItem.jsx, which would work fine if I only had one Menu Item/Command. Here is what I have. I obviously don't understand the 'this' object or how to separate the Commands. Help much appreciated.
function SnpAddMenuItem()
          this.requiredContext = "\tAdobe Bridge must be running.\n\tExecute against Bridge CS5 as the target.\n";
          this.menuID = "snpAddMenuItem";
          this.menuCommandID = "snpAddMenuItemSub";
          $.level = 1; // Debugging level
SnpAddMenuItem.prototype.run = function()
          var retval = true;
          if(!this.canRun()) {
                    retval = false;
                    return retval;
    var newMenu = new MenuElement( "menu", "Scanning", "after Window", this.menuID );
    var stackCommand = new MenuElement( "command", "Gather NNYY Into Stacks", "at the end of " + this.menuID, this.menuCommandID );
    var maskCommand = new MenuElement( "command", "Process Stacks into Layers", "at the end of " + this.menuID, this.menuCommandID );
          stackCommand.onSelect = function()
                    var scriptFilePath = "~/Documents/Adobe Scripts/AutostackNNYY.jsx";
         var scriptFile = new File (scriptFilePath);
         $.evalFile( scriptFile );
    return retval;
          maskCommand.onSelect = function()
                    var scriptFilePath = "~/Documents/Adobe Scripts/StacksToLayers.jsx";
         var scriptFile = new File (scriptFilePath);
         $.evalFile( scriptFile );
          return retval;

This will put the two commands at the bottom of the Tools menu....
#target bridge  
   if( BridgeTalk.appName == "bridge" ) { 
var stackCommand = new MenuElement( "command", "Gather NNYY Into Stacks", "at the end of Tools","uniqueId1");
var maskCommand = new MenuElement( "command", "Process Stacks into Layers","at the end of Tools","uniqueId2");
stackCommand.onSelect = function () {
//Your code goes here
maskCommand.onSelect = function () {
//Your code goes here
