Affiliate Application: Website Verification

[Elby]

To gain access to an affiliate program I am being asked the following:

• Copy the JavaScript below.
• The JavaScript can be placed in one of the following places:
  • Locate your homepage. This is probably named "index.html" or "index.php" in your web root directory (likely to be named "public_html"). You may need to check with your host to determine what file this is. Paste the JavaScript anywhere in that file and save the file to your web server.
  • Paste the JavaScript anywhere within the template that is used on the homepage of your site.
• Click the following link to verify the placement of Javascript: https://classic.avantlink.com/affiliate_app_confirm.php?mode=verify-js&application_id=12
• If your application confirmation was successful, you can delete the JavaScript from your homepage or template.

Can somebody show me where to paste in the Javascript to satisfy this affiliate program owner?
