Unable to invoke CFC - Variable Q is undefined

I am using Ms sql and if I do this in the query editor :

select dbo.GetBranchNoFromIP('9.4.1.42')

I get a good result,

however in a remote object if I do the following:

<cffunction name="getCode" access="remote" returntype="string">       
        <cfargument name="localIP" type="string" required="yes">      

       
        <cfstoredproc  procedure="GetBranchNoFromIP"   datasource="#datasource#" returncode="true">
       
            <cfprocparam type="in" cfsqltype="CF_SQL_VARCHAR" value="9.4.1.42">
            <cfprocresult name="q">

       
        </cfstoredproc>   
       
       
        <cfset flash.result=q>   
        <cfreturn flash.result>                   
    </cffunction>  

I get an error sayuing

faultCode:Server.Processing faultString:'Unable to invoke CFC - Variable Q is undefined.' faultDetail:''

ANy ideas what could be wrong?
