Constructor functions must be instance methods?

Question

Hi,
I have this code as in the following:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
    <mx:Script>
        <![CDATA[
            import mx.controls.*;           
            import mx.events.*;
            import mx.containers.*;       
            import thematicMap.*;  
             public var Region:Region = new Region();
             public var Scale:Scale = new Scale();
             public var ThematicMap:ThematicMap = new ThematicMap(); //1026:Constructor functions must be instance methods
             public var ReadXML:ReadXML = new ReadXML();       
             private var savedIndex:int= 99999;        
              public function addNavigation():void{
                  var buttonTools:Array = ["Driving Distance","Education Level--College",
                                           "Education Level--High School","Median Income","Population"];
                  var navigationBar:ToggleButtonBar = new ToggleButtonBar();
                      navigationBar.dataProvider = buttonTools;
                      navigationBar.toggleOnClick = true;
                      navigationBar.selectedIndex = -1;
                      navigationBar.addEventListener(ItemClickEvent.ITEM_CLICK,clickHandler);                      
                      //pass the variables?
                      addSlider(); //add the slider control  
                      vbox.addChild(navigationBar);
              public function addSlider():void{
                   var text_entry:HBox = new HBox();                 
                   var numColors:TextInput = new TextInput();
                       numColors.length == 3;
                       numColors.text = "5";
                       numColors.restrict = "0-9";
                   var direction:Text= new Text();
                       direction.text = "Number of Colors";
                    //recalculate the map if the listener is called
                   text_entry.addChild(direction);
                   text_entry.addChild(numColors);
                   vbox.addChild(text_entry);                    
             public function clickHandler(event:ItemClickEvent):void{
                 if(event.index == savedIndex) {
                     //don't do a thing
                 else savedIndex = event.index;           
                 //add the thematic map                
                 ThematicMap.addRegions(OK); //This part never worked
                 //mapGrid.addChild(thematicmap);
        ]]>
    </mx:Script>
   <mx:Canvas id="map" creationComplete="addNavigation()">
           <mx:VBox id="vbox" x="20" y="10">           
           <mx:Canvas id="mapGrid"/>      
    </mx:VBox>     
   </mx:Canvas>
</mx:Application>
Here is what I have in my ThematicMap.as:
package thematicMap
    import mx.core.*;
    import mx.events.*;
    public class ThematicMap {       
        public var region:Region = new Region();  
        public var readXML:ReadXML = new ReadXML();     
        public function addRegions(name:String):void {   
             trace(name);      
Have I done something wrong here? How come it keeps telling me that the constructor functions must be instance methods?
Thanks for your help.
Alice

Yes, I put in the quotes, and that took care of that error.
However, it still tells me I have an error that I am calling a possibly undefined method addRegions through a reference with static type ThematicMap
Here is the complete code of my main app:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
    <mx:Script>
        <![CDATA[
            import mx.controls.*;           
            import mx.events.*;
            import mx.containers.*;       
            import thematicMap.*;   //I had imported all the classes
             public var region:Region = new Region();
             public var scale:Scale = new Scale();
             public var thematicMaps:ThematicMap = new ThematicMap();
             public var readXML:ReadXML = new ReadXML();       
             private var savedIndex:int= 99999;        
              public function addNavigation():void{
                  var buttonTools:Array = ["Driving Distance","Education Level--College",  "Education Level--High School","Median Income","Population"];
                  var navigationBar:ToggleButtonBar = new ToggleButtonBar();
                      navigationBar.dataProvider = buttonTools;
                      navigationBar.toggleOnClick = true;
                      navigationBar.selectedIndex = -1;
                      navigationBar.addEventListener(ItemClickEvent.ITEM_CLICK,clickHandler);                      
                      //pass the variables?
                      addSlider(); //add the slider control  
                      vbox.addChild(navigationBar);
              public function addSlider():void{
                   var text_entry:HBox = new HBox();                 
                   var numColors:TextInput = new TextInput();
                       numColors.length == 3;
                       numColors.text = "5";
                       numColors.restrict = "0-9";
                   var direction:Text= new Text();
                       direction.text = "Number of Colors";
                    //recalculate the map if the listener is called
                   text_entry.addChild(direction);
                   text_entry.addChild(numColors);
                   vbox.addChild(text_entry);                    
             public function clickHandler(event:ItemClickEvent):void{
                 if(event.index == savedIndex) {
                     //don't do a thing
                 else savedIndex = event.index;           
                 //add the thematic map                
                 thematicMaps.addRegions("OK");
                 //mapGrid.addChild(thematicmap);
        ]]>
    </mx:Script>
   <mx:Canvas id="map" creationComplete="addNavigation()">
           <mx:VBox id="vbox" x="20" y="10">           
           <mx:Canvas id="mapGrid"/>      
    </mx:VBox>     
   </mx:Canvas>
</mx:Application>
As a matter of fact, when I write import thematicMap. it looks like thematicMap.ThematicMap does show up, so that is imported, right?
I am getting confused.
