How to add a counting system to randomiser?

I have a randomiser, and I want to add a counting system that shows how many times a certain result came out. For example: if I enter Hello and Goodbye, it has to count the times Hello came out, same for Goodbye. If possible, users have to select the max. score they want. For example: 3/5, 5/7 etc... Can you also put a reset button in the code to reset the code and the scores? Here's my code for the randomiser:

<script src="http://ift.tt/1oMJErh"></script>      
  <form>
  <hr/>
    <a href="javascript:;void(0);" id="buttonOne">Insert input form</a>
  <hr/>

    <input type="submit" value="Post the form" /> 

  </form>

  <script type="text/javascript">
    var sequence = 0;
    $(document).ready(function(){

        $("#buttonOne").click(function(){
            $("form").prepend("<input name=name"+sequence+" placeholder='something' type='text' /> <br/> ");
            sequence++;
        });

        $("form").submit(function(e){

            $('input[type=text]').each(function(){
               if($(this).val() == "") $(this).remove();
            });

            if( $('input[type=text]').size() >= 2  ){

              random_number = parseInt( Math.random() * $('input[type=text]').size() );

                alert(  $('input[type=text]:eq('+random_number+')').val()  );

             }else{
              alert("sorry you need at least 2 fields");

             }
              return false;
        });

    });

  </script>

Thanks a lot for helping me out!
