A VoiceXML error occurred of type "error.badfetch": Form id attribute 'start' is not unique

Hi All,

         This is what I got when I want to repeat an audio for n number of times. In my requirement, I need to prompt a menu  which took dtmf as input, if user enter 9 as dtmf , I need to prompt an audio n number of times. The  number of iterations can get from configuration of Voice element. I attached my code with this post, can any one guide where I went wrong. 

this how my code look likes, I used for loop to repeat a menu for n number of times.

VPreference pref = ved.getPreference();

  String submittedMainFieldName =(String) ved.getScratchData(AUDIO_NAME);

  VoiceElementConfig conf=ved.getVoiceElementConfig();

  String some= conf.getSettingValue(OPTION_DTMF, ved);

  String menuOption = null;

         if (submittedMainFieldName!=null) {

          System.out.println("first time its null second time check what will happen");

          menuOption = (String)reqParameters.get(submittedMainFieldName);

         }

  if(null==menuOption){

  VForm form=new SampleVFCElement().getVForm(pref, ved);// this method will build menu options

  vxml.add(form);

  ved.setScratchData(AUDIO_NAME, "Mfield");

  return null;

  }else if(menuOption.equals("9")){

  for(int i=0;i<3;i++){

  System.out.println("repeat block "+i);

  VForm prompt_form = VForm.getNew(pref, "start");

                 VBlock prompt_block = VBlock.getNew(pref);

                 prompt_form.add(prompt_block);  

                 VAudio media_item=VAudio.getNew(pref, null,null,"this will repeat ",".wav");

                 prompt_block.add(media_item);

                 VAction prompt_submit = VAction.getNew(pref);

                 prompt_submit.add(getSubmitVAction(null, pref));

                 prompt_block.add(prompt_submit);

                 vxml.add(prompt_form);

  }

    return "done";

  }

  else{

  System.out.println("some thing ");

  }

Can any one please help me out of this, I attached my code .

you can call your form almost anything except 'start' - that's reserved.

Call it something else.
