Flash remoting

Hello,
I would like to get a variable back using flash remoting. Below is the code I am using :

Action script :

#include "NetServices.as"

if(inited == null)

{

 inited=true;

 NetServices.setDefaultGatewayUrl("
http://localhost:8500/flashservices/gateway");

 var connexion = NetServices.createGatewayConnection();

 var myservice =
connexion.getService("com.macromedia.test.toto", this);

 

 myservice.toto({param1:1002});

}

.cfc :

<cfcomponent>



 <cffunction name="toto" returnType="numeric"
access="Remote">

 <cfargument name="param1" type="numeric"
required="yes">

 <cfreturn param1>

 </cffunction>

 

</cfcomponent> 

.cfm :

<cfoutput>

 <cfinvoke component="com.macromedia.test.toto"
method="toto" returnvariable="valeur">

 #valeur#

</cfoutput>

Serveur connexion works, but I get an error stating that the variable is not defined.
Thank you for your help.
