[flexcoders] embedded swf not playing

[flexaustin]

I have an embedded swf that is not auto playing when it is imported
into Flex? Here is the code (below). When my flex swf is run the swf
just sits there, but the code in my swf says onEnterFrame rotate in a
circle.  Any suggestions?  

<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml";
creationComplete="init()"
        
         width="24" height="24">
        <mx:Script>
                <![CDATA[
                        
                        
                        [Embed(source="/assets/images/LoadingAnimation.swf",
symbol="CircleOfOranges")]
                        [Bindable]
                        public var LoadingAnim:Class;

            
 
            
            
            
        ]]>
    </mx:Script>
        <mx:HBox width="24" height="24" verticalCenter="0" left="0">
                <mx:Image id="loadinganim" source="{LoadingAnim}" width="24"
height="24"  scaleContent="true"/>
        </mx:HBox>

   
           
</mx:Canvas>
