Context Menu

I can't get my context menu to work with my plugin. Alos, I am trying to get it to create a fake image so that there is something there in the editor.

Here is my code:

// Context menu
FCK.ContextMenu.RegisterListener( {
   AddItems : function( menu, tag, tagName )
   {
      // under what circumstances do we display this option
      if ( tagName == 'IMG' && tag.parsedMap )
      {
         // No other options:
         menu.RemoveAllItems() ;
         // the command needs the registered command name, the title for the context menu, and the icon path
         menu.AddItem( 'yahoo_maps', FCKLang.DlgGyahoo_mapsTitle, oyahoo_mapsItem.IconPath ) ;
      }
   }}
);

// Check if the comment it's one of our scripts:
var yahoo_maps_CommentsProcessorParser = function( oNode, oContent, index)
{
      var oMap = new FCKyahoo_maps();
      
      if ( oMap.parse( oContent ) )
         oMap.createHtmlElement( oNode, index ) ;
      else
      {
         if ( oMap.detectGoogleScript( oContent ) )
            oNode.parentNode.removeChild( oNode );
      }
}

FCKCommentsProcessor.AddParser( GoogleMaps_CommentsProcessorParser );



// Double click

FCK.RegisterDoubleClickHandler( editMap, 'IMG' ) ;

function editMap( oNode )
{
   if ( !oNode.parsedMap)
      return ;

   FCK.Commands.GetCommand( 'yahoo_maps' ).Execute() ;
}
FCKyahoo_maps.prototype.createHtmlElement = function( oReplacedNode, index)
{
   var oFakeNode = FCK.EditorDocument.createElement( 'IMG' ) ;

   // Are we creating a new map?
   if ( !oReplacedNode )
   {
    index = FCKTempBin.AddElement( this.BuildScript() ) ;
      var prefix = ( FCKConfig.ProtectedSource._CodeTag || 'PS..' ) ;
      oReplacedNode = FCK.EditorDocument.createComment( '{' + prefix + index + '}' ) ;
      FCK.InsertElement(oReplacedNode);
   }
   oFakeNode.contentEditable = false ;
//   oFakeNode.setAttribute( '_fckfakelement', 'true', 0 ) ;
   oFakeNode.src = FCKConfig.FullBasePath + 'images/spacer.gif' ;
   oFakeNode.setAttribute( '_fckrealelement', FCKTempBin.AddElement( oReplacedNode ), 0 ) ;
   oFakeNode.setAttribute( '_fckBinNode', index, 0 ) ;

   oFakeNode.style.display = 'block' ;
   oFakeNode.style.border = '1px solid black' ;
   oFakeNode.style.background = 'center center url("' + FCKPlugins.Items['yahoo_maps'].Path + 'images/maps_res_logo.png' + '") no-repeat' ;

   oFakeNode.parsedMap = this ;

   oReplacedNode.parentNode.insertBefore( oFakeNode, oReplacedNode ) ;
   oReplacedNode.parentNode.removeChild( oReplacedNode ) ;

   // dimensions
   this.updateHTMLElement( oFakeNode );

   return oFakeNode ;
}

Please Help, Thank you much!
