What data format for "add_response" parameter (RPC) - by: frajos100

Hi,
I am trying to consume the same exact method in my .Net Application.
But everytime i am getting Result = null.


Paramater that I am passing using Json RPC
{"jsonrpc":"1.0","id":"1","method":"Add_Reponse","params":{"sessionkey":"ABCD","surveyID":"919472","aResponseData":{"submitdate":"07/22/2013","lastpage":"1","startlanguage":"en","919472X6X10":"Y","919472X6X11":"my feedback to you","919472X6X12":"4"}}}

Also i tried the following
{"jsonrpc":"1.0","id":"1","method":"Add_Reponse","params":{"sessionkey":"ABCD","surveyID":"919472","aResponseData":{"919472X6X10":"Y","919472X6X11":"my feedback to you","919472X6X12":"4"}}}
But the Survey response is not getting Added.

The Survey is an Open ended one.

Any pointers as to how to get it working.
