title: Add value of ACF field to Gravity Form in current Custom Post type page
body: <p>I have a Custom Post Type called "Profile". With <a href="https://www.advancedcustomfields.com" rel="nofollow">Advanced Custom Fields</a> (ACF) I've added the additional field <strong>PDF_file</strong>, which is used to upload a file to the newly created post, and on the frontend is a button linked to the uploaded file.</p>
  
  <p>Using Gravity Forms I want visitors to be able to send this file to a friend by sending the file link, which is basically the value of the "<em>PDF_file</em>" field.</p>
  
  <p>I can't seem to find out how I can retreive the value and insert it in to the Gravity Form.</p>
  
  <p>I have implemented the Gravity in the single custom post type template by using:</p>
  
  <pre><code>&lt;?php gravity_form(15, $display_title=false, $display_description=true, $display_inactive=false, $field_values=null, $ajax=true, $tabindex); ?&gt;
  </code></pre>
