How can I stop Bind from returning both forms in MVC?

I am dynamically building pages with forms from my db, which means I can have 1 form or many per page.

All of my forms have unique Ids and Submit buttons, however within each form the ids and names of the inputs are the same.

<form action="/" class="form-horizontal" id="form1" method="post" role="form">    <h1>1. What is your favourite colour?</h1>
    <select class="form-control" id="Answer" name="Answer">
          <option value="red">red</option>
          <option value="blue">blue</option>
          <option value="yellow">yellow</option>
          <option value="green" selected>green</option>
          <option value="lavender">lavender</option>
    </select>
    <input type="hidden" name="page" id="page" value="1" />
    <input type="submit" name="form1" class="btn btn-default" value="Save answer" />

<form action="/" class="form-horizontal" id="form2" method="post" role="form">    
<h1>2. Do you own a car?</h1>
    <input type="radio" name="Answer" id="Answer" value="yes" />yes               
    <input type="radio" name="Answer" id="Answer" value="no" />no                
    <input type="radio" name="Answer" id="Answer" value="maybe!" />maybe!  
<input type="hidden" name="page" id="page" value="1" />
<input type="submit" name="form2" class="btn btn-default" value="Save answer" />

My post action looks like this;

[HttpPost]
 public ActionResult ViewQuestion([Bind(Include = "QuestionId, Answer, UserId")] ResponseViewModel responseViewModel)
  {
     var page = System.Web.HttpContext.Current.Request["page"];

In this example, instead of receiving "1" for "page" variable, I am getting "1,1".

Is there a way I can bind to the value from the ONE form that is being submitted?
