title: Visual Studio Web Performance Test - Dynamic Querystring Parameter from Hidden Field
body: <p>We have an application that generates Quotes. In the early stages of the application a unique QuoteId is generated. This id can be found in a hidden field, that is sent to the client in an MVC Partial View (over an ajax request).</p>
  
  <p>I need to be able to extract this hidden field, and then reuse the value in subsequent requests. I can see how to add dynamic query string parameters, but my attempts so far to extract the id have not worked.</p>
  
  <p>So far I have been focusing on extraction rules on the previous request to try and get the data (I've tried extracting both Form Fields and Hidden Fields). </p>
  
  <p>Any help would be appreciated.</p>
  
  <p>Thanks</p>
