How do I upload additional data alongside image upload?

[John_Locke_2013]

How do I upload additional variables alongside an image upload? My code doesn't seem to be working.            temp.upload(new URLRequest(serverURL));           var variables:URLVariables = new URLVariables();                           variables.my_name = "Jackson" ;                 variables.my_state = "Missisippi" ;                            var request:URLRequest = new URLRequest(serverURL);           request.method = URLRequestMethod.POST;                      // Put parameters into request.data           request.data = variables;                                     // Perform the upload           temp.upload(request);
