[flexcoders] Class file in flex

[litesh_b321]

hi guys,
 I am trying action script class in flex 3.0

I have action script class in "Inculdes\ClassTesting.as" directory
which is situated inside src directory. 

See code below :
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";
layout="absolute">
<mx:Script>
        <![CDATA[
                import Inculdes.ClassTesting;
                import mx.messaging.AbstractConsumer;
                include "Inculdes/ClassTesting.as";
                public function ansT():void
                  {
                        ans.text = tester( frst.text,scnd.text);
                        
                  }
                ]]>
</mx:Script> 
        <mx:Button x="52" y="192" label="Button" id="b1"   click="ansT()"
borderColor="#10DD10" height="26" width="69"/>  
        <mx:Text x="52" y="77" text="12" width="293" id="frst" visible="true"/>
        <mx:Text x="52" y="103" text="23" width="293" id="scnd" visible="true"/>
        <mx:Text x="52" y="155" text="34" width="293" id="ans" visible="true"/> 
</mx:Application>
