Anyone know whay I am getting this error?

Question

Variable qUpdateVersion is undefined.
Here is my function:
    <cffunction name="UpdateVersion" access="public" returntype="query">
        <cfquery name="qUpdateVersion" datasource="ProjectMatrix">
            UPDATE tblProjectTracking
            SET dateRemoved=#form.dateRemoved#,dateToTakeDown=#form.dateToTakeDown#
            WHERE ID = #form.ID#
        </cfquery>
      <cfreturn qUpdateVersion> 
    </cffunction>
Here is my Invoke:
<cfinvoke
  component="hardy.Operations.components.Query"
  method="UpdateVersion"
  returnVariable="qUpdateVersion">
</cfinvoke>
I don't understand the error. My query looks good as it is just pulling 2 items from the previous pages form. I ran a CFDUMP and verified that the variables needed are being passed. When I remove the cfdump, I get this error and it is driving me mad. I am using coldfusion 8. I am missing something that is obviously going right over my head.

It would also be a good idea to pass in the id value, rather then relying on the component function to get the data from the form scope outside of itself.
Depending on where the component is coming from, it may or may not have access to the form scope.
    <cffunction name="UpdateVersion" access="public" returntype="query">
        <cfargument name="id" type="numeric">
        <cfset var qUpdateVersion = "">
        <cfquery name="qUpdateVersion" datasource="ProjectMatrix">
            UPDATE tblProjectTracking
            SET dateRemoved=#form.dateRemoved#,dateToTakeDown=#form.dateToTakeDown#
            WHERE ID = #arguments.ID#
        </cfquery>
      <cfreturn qUpdateVersion> 
    </cffunction>
<cfinvoke
  component="hardy.Operations.components.Query"
  method="UpdateVersion"
  id="#form.id#"
  returnVariable="qUpdateVersion">
</cfinvoke>
