dsn in user defined functions

hey, I'm a newbie in coldfusion. Have been stuck with this problem for a week now... Hope somebody could help...

I implemented a related select on a form:

<table>

        <tr>

       <td>Select Level:</td>

       <td><cfselect name="level_id" id="level_id"

           bind="cfc:myfuncs.getLevel()"

           bindonload="true" value="level_id" display="level_name"  /></td>

       </tr>

       <tr>

       <td>Select Class:</td>

       <td><cfselect name="class_id"

              bind="cfc:myfuncs.getClasses({level_id})" value="class_id" display="class_id" /></td>

       </tr>

</table>

Meanwhile myfuncs.cfc looks like this:

<cfcomponent output="false">

   <cfset THIS.dsn="#Request.DSN#">

   <cffunction name="getLevel" access="remote" returnType="array">
      <!--- Define variables --->
      <cfset var data="">
      <cfset var result=ArrayNew(2)>
      <cfset var i=0>

      <!--- Get data --->
      <cfquery name="data" datasource="#THIS.dsn#">
      <cfquery name="data" datasource="#THIS.dsn#">
              SELECT level_id, level_name
               FROM tbLevel
                ORDER BY level_id
      </cfquery>

      <!--- Convert results to array --->
      <cfloop index="i" from="1" to="#data.RecordCount#">
         <cfset result[1]=data.level_id>
         <cfset result[2]=data.level_name>
      </cfloop>

      <!--- And return it --->
      <cfreturn result>
   </cffunction>

<cffunction name="getClasses" access="remote" returnType="array">
      <cfargument name="level_id" type="numeric" required="true">

      <!--- Define variables --->
      <cfset var data="">
      <cfset var result=ArrayNew(2)>
      <cfset var i=0>

      <!--- Get data --->
      <cfquery name="data" datasource="#THIS.dsn#">
      SELECT class_id, class_day, class_time, class_size, start_dt, end_dt
      FROM tbClass
      WHERE level_id = #ARGUMENTS.level_id#
      ORDER BY class_day
      </cfquery>
 
      <!--- Convert results to array --->
      <cfloop index="i" from="1" to="#data.RecordCount#">
   
         <cfset result[1]=data.class_id>
         <cfset result[2]=data.class_day&" "&data.class_time>
         <cfset result[3]=data.class_size>
         <cfset result[4]=data.start_dt>
         <cfset result[5]=data.end_dt>  
      </cfloop>

      <!--- And return it --->
      <cfreturn result>
   </cffunction>

</cfcomponent>

My Application.cfm file contains:

<cfparam name="Request.DSN" default="mydsn">

<cfparam name="Request.username" default="myuser">

<cfparam name="Request.password" default="mypass">

But my drop-list is just empty on the form. No errors. Coldfusion version is 8 and the server is a multi-home server.

Could any expert shed some light on this?

Thanks!
