Command not working for group

What steps will reproduce the problem?
1. I have downloaded this json file from Http://media.mongodb.org/zips.json
2. execuded this command line : mongoimport --db scratch --collection zips 
--file zips.json
3. and in the Tools->Command pasted :
{
  group : 
  {
    ns : 'zips',
    key : {'state':1},
    initial : {'pop' : 0 },
    $reduce : function (curr,result)
    {
    //if(curr.pop>result.pop)
    {result.pop += curr.pop;}
     } 
  }
}
for DB:scratch and Format:JSON
4. press on execute button and i'll get this error message :
Response from server:
{
   "errmsg": "exception: not code",
   "code": NumberInt(10062),
   "ok": 0
}   
this works with mongo command line!
