[flexcoders] dynamic move

[[EMAIL PROTECTED]]

In this code I'm dynamically creating an HBox, adding an image to it, 
adding the box to a Panel,  and then creating a Move() to move the Hbox.
It produces the error below, which says "value" is not a function. WHAT 
VALUE? Why doesn't it name the value ?  What did I do wrong ?
The error comes when I add the final line, moveSketch.play();



var sketchBox:HBox = new HBox();
               var sketchImg:Image=new Image;
               sketchImg.source="Journeysketchsm.gif";
               sketchBox.addChild(sketchImg);
               thePanel.addChildAt(sketchBox,0);
                    
                var moveSketch:Move = new Move();
                moveSketch.target="sketchBox";
                moveSketch.xTo=150;
                moveSketch.duration=3000;
                moveSketch.play();
                         

TypeError: Error #1006: value is not a function.
