Flexible loop variable into functions

Hi guys. Was hoping for a bit of help on this. I currently have a function in my functions.php file the allows the addition of shortcode on Contact Form 7, like so:

wpcf7_add_shortcode('wpcf7_doclink', 'add_doclink', true);

function add_doclink() {

  if($the_file_url){
    $html = '<input type="hidden" name="your-doclink" value="'.$the_file_url.'">';
  }
  else{
    $html = null;
  }
  return $html;
}

In my template file I have the a flexible content loop which I would like to use a sub field from in the above function:

<?php if( have_rows('level') ): ?>
    ...
    <?php while ( have_rows('level') ) : the_row(); ?>

        <?php if( get_row_layout() == 'download_form' ): ?>
            ...      
             <?php $the_file_url =  get_sub_field('document_file')?>
            ...
        <?php endif; ?>
        ...
    <?php endwhile; ?>

<?php endif;?>

The problem seems to be the scope of the variables. I can’t get the variable $the_file_url into the function. Can anyone help with this? The function works if it isn’t in a flexible loop.
