Problem calling function via flashVars

[maxwell5]

I have a working flash banner with three buttons leading to other web pages.
I would like to have the same banner on more of my web pages.

I am trying to use flashVars to send a variable to the banner letting is know which fucntion to run.
The banner has multiple function blocks each relating to a particular web page.
The web pages will each have a flashVars variable, that will call its related function block.

I have added the banner to one of the web pages however the buttons are
unresponsive when tested.

Please see following code -

Example of flashVars variable on banner web pages

 <param name=FlashVars value="myFlashVar=testFlashVar" />

Code contained within flash banner

import flash.events.MouseEvent;
import flash.net.URLLoader;


// set a variable to hold the value of our first flashvar
var myFlashVar:String = "testFlashVar"; 

// set a variable to hold the value of our second flashvar 

var myFlashVar2:String = "secondtest"; 

// set a variable to hold the value of our third flashvar 

var myFlashVar3:String = "anothertest"; 

// set an object to hold all of the parameters (flashvars) passed in from the html 

var paramObj:Object=LoaderInfo(this.root.loaderInfo).parameters; 

function checkForFlashVars():void { 

   // check to see if myFlashVar has a new value passed in from the html; if it does, use this value instead 

   if (paramObj.xmlpath) { 

      myFlashVar = String(paramObj.myFlashVar); 

	  computers_comp();
    }
 
   if (paramObj.myFlashVar2) { 

      myFlashVar2 = String(paramObj.myFlashVar2); 

 	  computers_publicaccess();
 
   }
   
    if (paramObj.myFlashVar3) { 

      myFlashVar3 = String(paramObj.myFlashVar3); 

	  computers_staff();
 
   }
}
 
// call the function
 
checkForFlashVars();
