Carry a field in WebForm
You can achieve it as follows:


Copy webform-confirmation.tpl.php from /webform/templates and into your theme's template folder
Rename it to webform-confirmation-{nid}.tpl.php to apply the template to a specific webform
Make sure you clear Drupal's cache after placing or renaming the template file
Add the following snippet

include_once drupal_get_path('module','webform') . '/includes/webform.submissions.inc';
$submission = webform_get_submission($node-&gt;nid, $sid);
// All the submitted values will be here, access the necessary values from this object.
// print_r($submission); 



I tried this snippet, and it works. It was taken from Print submitted data on confirmation page.
